A solution containing 4.2 g of KOH and `Ca(OH)_(2)` is neutralised by an acid. If it consumes 0.1 g equivalents of the acid, calculate the composition of the sample.

A solution containing 3.00 g of a monobasic organic acid was just neutralised by 40 mL of 05 N NaOH solution. Calculate the molecular weight of the acid.

320g mg of a sample of magnessium having a coasting of its oxide required 20mL of 0.1M hydrochloric acid for the complete neutralisation of the latter. The composition of the sample is:

0.126g of an acid is needed to completely neutralise 20 mL 0.1 N NaOH solution. The equivalent weight of the acid is-

Calculate the volume of 0.1 N H_(2)SO_(4) required to neutralise 200 ml. of 0.2 N NaOH solution. It is an acid base neutralisation reaction. Hence, at the neutralisation point. Number of equivalents of acid = Number of equivalents of base.

200 cm^(3) of a solution of a dibasic acid contains 1.512 g of the acid and the normality of the solution is 0.12. Calculate (i) the equivalent mass and (ii) the molecular mass of the acid.
