How much sodium hydroxide does it take to neutralize hydrochloric acid? (2023)

How much sodium hydroxide does it take to neutralize hydrochloric acid?

In the neutralization of hydrochloric acid by sodium hydroxide, the mole ratio of acid to base is 1:1. One mole of HCl would be fully neutralized by one mole of NaOH.

10 mL of a solution of NaOH is found to be completely neutralized by 8 mL of a given solution of HCl. If we take 20 mL of the same solution of NaOH, the amount of HCl solution (the same solution as before) required to neutralize it will be. No worries!

Complete solution:

It is a neutralization reaction in which base sodium hydroxide reacts with phosphoric acid and produces salt sodium phosphate that is salt and water. The stoichiometric mole ratio indicates 3 moles of sodium hydroxide are required to neutralize one mole of phosphoric acid.

So 0.4 gram of NaOH is required to neutralize 100 ml of 0.1N HCl.

Thus, 40 grams of $\text{NaOH}$ is required for complete neutralization.

Process of Neutralizing Hydrochloric Acid

Add 1M NaOH to the dilute HCl solution, testing with a pH meter or pH paper until it reaches a neutral pH between 6.0 and 8.0. Flush down drain while continuing to add cold water.

For example: In a simple neutralization process hydrochloric acid (HCl) can be neutralized by using sodium hydroxide (NaOH).

The correct option is C 6 g.

NaOH: HCl is 1:1, so n(NaOH) = n(HCl) = 0.003 moles at neutralization.

How much acid is needed to neutralize?

At the equivalence point in a neutralization, the moles of acid are equal to the moles of base, assuming they react in a 1:1 ratio according to the balanced neutralization equation.

The correct answer is 2. 2 grams of NaOH are needed to make 100 ml. of a 0.5 M solution of NaOH. So, mass of NaOH = 0.05*40 = 2 grams.

Thus the volume of concentrated HCl is 8.08L.

V=Eq. wt. ×Nw×1000=50×0. 11×1000=200cm3.

1 mole of sulfuric acid needs 2 moles of sodium hydroxide for its complete neutralization.

Calculating a volume

25.00 cm ³ of 0.300 mol/dm ³ sodium hydroxide solution is exactly neutralised by 0.100 mol/dm ³ sulfuric acid.

In other words, it takes 1 mole of hydroxide anions to completely neutralize 1 mole of hydronium cations. Consequently, you can say that it takes 1 hydroxide anion to completely neutralize 1 hydronium cation.

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H⁺ ions and OH^- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.

A neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H⁺ ions and OH^– ions which form water.

Neutralisation Reaction

When a strong acid reacts with a strong base the resultant salt is neither acidic nor basic in nature i.e. it is neutral. For example when HCl (Hydrochloric acid), a strong acid, reacts with NaOH, a strong base, the resulting salt is sodium chloride and water.

What happens if you mix sodium hydroxide and hydrochloric acid?

So, hydrochloric acid reacts with sodium hydroxide solution to form sodium chloride and water. This reaction can be represented as: Hydrochloric acid + Sodium hydroxide → Sodium chloride + Water.

1 mole HCl neutralizes by 1 mol baking soda. So,0.5 mole HCl neutralizes by 0.5 mol baking soda. Hence, 42 g of baking soda is needed to neutralize 500 mL of hydrochloric acid (1M).

To neutralize acids, a weak base is used. Bases have a bitter or astringent taste and a pH greater than 7. Common bases are sodium hydroxide, potassium hydroxide and ammonium hydroxide.

The pH neutralization of Hydrochloric acid is conventional and any inorganic base such as sodium hydroxide or lime can be used.

The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.

When HCl(aq) is exactly neutralized by NaOH(aq), the hydrogen ion concentration in the resulting mixture is always less than the concentration of the hydroxide ions.

Answer: Therefore, for example, if the NaOH is 10ml of 6N solution, either 10ml of 6N HCl is needed, 30ml of 2N HCl or 60ml of 1N HCl would be needed.

How many moles of NaOH are needed to neutralize 15.0 mL of 0.235 M HCl solution? a. 2.35 x 10−1 moles.

Neutralizing Hydrochloric Acid

Mix 1 lb of baking soda with plenty of water. Slowly add the hydrochloric acid. The mixture will fizz. Add more baking soda until the fizzing stops.

Measure approximately 50 mL of a sample in a 100 mL beaker using an electronic balance. Place the beaker on the magnetic stirrer, add a stir bar and stir slowly. Place the pH electrode in the solution. If the initial pH is less than 4.5 no titration is necessary and equation (45) can be used to calculate the ANC.

How do you neutralize an acid solution?

Adding a base decreases the concentration of H₃O⁺ ions in the solution. An acid and a base are like chemical opposites. If a base is added to an acidic solution, the solution becomes less acidic and moves toward the middle of the pH scale. This is called neutralizing the acid.

So, hydrochloric acid reacts with sodium hydroxide solution to form sodium chloride and water. This reaction can be represented as: Hydrochloric acid + Sodium hydroxide → Sodium chloride + Water.

The correct option is C 6 g.

Sodium hydroxide is easy to handle, inexpensive, and very effective for the neutralization of strong or weak acids.

Hint:Sodium hydroxide is a base, when it reacts with hydrochloric acid acid-base reaction will happen. The formula of sodium hydroxide and hydrochloric acid are, NaOH, HCl. Sodium hydroxide is a strong base, but hydrochloric acid is a strong acid.

A 100ml solution of 0.1N HCl was titrated with 0.2N NaOH solution . The titration was discontinued after adding 30ml of NaOH solution . The remaining titration was completed by adding 0.25 N KOH solution .

Titrations. When hydrochloric acid is reacted with sodium hydroxide, an acid/base mole ratio of 1:1 is required for full neutralization.

48.0 pounds of sodium hydroxide are needed to neutralize the sulfuric acid.

Regardless of how the equation is written, one mole of acetic acid in the vinegar requires one mole of sodium hydroxide to get neutralized.

How do you neutralize acid quickly?

The pH neutralization of Hydrochloric acid is conventional and any inorganic base such as sodium hydroxide or lime can be used. Hydrochloric acid is a one normal solution which means that for each mole of HCl one mole of H+ or acid is liberated requiring one mole of hydroxide (OH-) to neutralize.
