What happens when you titrate NaOH with HCl?

What happens when you titrate NaOH with HCl?

This reaction states that 1 molecule of HCl will react with 1 molecule of NaOH to produce 1 molecule of the salt, sodium chloride (NaCl), and 1 molecule of water.

How do you find the concentration of HCl from titration with NaOH?

1. Volume of sodium hydroxide solution = 25.00 ÷ 1000 = 0.0250 dm 3
2. Amount of sodium hydroxide = 0.200 × 0.0250 = 0.005 mol.
3. From the equation, 0.005 mol of NaOH reacts with 0.005 mol of HCl.
4. Volume of hydrochloric acid = 22.70 ÷ 1000 = 0.0227 dm 3
5. Concentration of hydrochloric acid = 0.005 mol ÷ 0.0227.
6. = 0.220 mol/dm 3

5. Answer.
6. MacidVacid = MbaseVbase

How many mL of NaOH will be needed to neutralize all of the HCl?

In this case, it just so happens to also be table salt (NaCl). We changed 500 mL into 0.5 L because molarity is per L not per mL. Therefore, we will need about 2.5 L of sodium hydroxide to neutralize the hydrochloric acid.

How do you titrate hydrochloric acid?

procedure

1. Pipette aliquot of hydrochloric acid solution into 250mL Erlenmeyer flask.
2. Dilute with distilled water to about 100 mL.
3. Add 2-3 drops of phenolphthalein solution.
4. Titrate with NaOH solution till the first color change.

Why do we use NaOH in titration?

The colorless sodium hydroxide NaOH(aq), which is the titrant, is added carefully by means of a buret. The volume of titrant added can then be determined by reading the level of liquid in the buret before and after titration. Titrant (NaOH) is added until it neutralizes all of the analyte (acetic acid).

Which indicator is suitable for the titration of HCl and NaOH and why?

For a weak acid vs strong alkali titration, phenolphthalein is the most suitable indicator. This is so because the last drop of added alkali brings the pH of the solution in the range in which phenolphthalein shows sharp colour change.

How do you standardize HCl with NaOH?

Standardisation procedure One way of doing this (for a 0.1M NaOH solution) is to pipette 20.00 mL of standard 0.100 M HCl into a flask and adding a couple of drops of phenolphthalein indicator. Then fill your burette with the NaOH solution and titrate the HCl until the colour changes to a pale permanent pink.

What neutralizes hydrochloric acid?

Acid Spills (hydrochloric or sulfuric acid): Neutralize spill with sodium bicarbonate/baking soda 2.

How much solid NaOH is required to neutralize?

And this would be how many grams? to convert from g NaOH to mol NaOH. = 1.48 g NaOH are needed to neutralize the acid.

What is the reaction between HCl and NaOH?

The reaction in which hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH) to produce water (H2O) and sodium chloride (NaCl) is a special type of double displacement reaction called a neutralization reaction. In a double displacement reaction,…

What happens when you mix NaOH and HCl?

When HCL and NaOH are mixed together then HCL dissociates into H+ ion and Cl- ion and NaOH dissociates into NA+ and OH-. so respective ions combine together to form NaCl and H20.

What is the chemical equation for HCl and NaOH?

NaOH is a base and HCl is an acid. An acid and base always react to form a salt and water, and it is called neutralization.The salt formed in this reaction is sodium chloride, NaCl . The equation for the reaction is: NaOH + HCl = NaCl + H2O. The numbers of Na, O, H and Cl atoms on the left and the right sides are as such equal.

Why is KHP used to standardize NaOH?

Standardization is typically carried out by titrating the NaOH solution with a primary standard, an ultra-pure, easily soluble acid such as potassium hydrogen phthalate (KHP). Unlike NaOH, KHP can be used to prepare a solution whose concentration is known with a high degree of precision.
