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

1.45g of succinic acid (C₄H₆O₄), a dibasic acid, was dissolved in deionised water and made up to 100cm³ in a volumetric flask.

10.0cm³ samples were titrated against sodium hydroxide solution of concentraion 0.100 mol dm^-3.

A mean titre of 23.40cm³ of sodium 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!)

1.04g of sodium hydroxide was dissolved in deionised water and made up to 100cm³ in a volumetric flask.

10.0cm³ samples were titrated against hydrochloric acid solution of concentraion 0.100 mol dm^-3.

A mean titre of 22.10cm³ of hydrochloric 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!
