Titration Based Problems Random Retrieval

This quiz contains all the questions in the Titration Based Problems section. The website will pick 10 questions at random.

1 / 10

0.368g of sodium hydroxide was dissolved in deionised water and made up to 100cm³ in a volumetric flask.

25.0cm³ samples were titrated against nitric acid solution of concentraion 0.100 mol dm^-3.

A mean titre of 20.75cm³ of nitric acid solution was obtained.

Calculate the percentage purity, by mass, of the original solid. (Don't include the % symbol and give answer to 1 decimal place!

0.925g of lithium hydroxide was dissolved in deionised water and made up to 250cm³ in a volumetric flask.

25.0cm³ samples were titrated against sulfuric acid solution of concentraion 0.100 mol dm^-3.

A mean titre of 13.75cm³ of sulfuric acid solution was obtained.

Calculate the percentage purity, by mass, of the original solid. (Don't include the % symbol and give answer to 1 decimal place!)

5 / 10

Calculate the pH of a solution created by the addition of 20.0cm³ 0.200 mol dm^-3 potassium hydroxide solution to 50.0 cm³ 0.100 mol dm^-3 nitric acid solution.

Remember to give your answer to 3 sig.fig.

6 / 10

By titration, it was found that an average titre of 9.90cm³ of 1.00 mol dm^-3 solution of potassium carbonate was required to just neutralise a 25.00 cm³ sample of sulfuric acid solution. Calculate the concentraion of the sulfuric acid solution.
