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

0.925g 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!)

16.1g of citric acid monohydrate (C₆H₈O₇.H₂O), a tribasic acid, was dissolved in deionised water and made up to 250cm³ in a volumetric flask.

10.0cm³ samples were titrated against potassium hydroxide solution of concentraion 0.500 mol dm^-3.

A mean titre of 18.10cm³ of potassium hydroxide 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!)
