`10cm^(3)` of 0.1N monobasic acid requires `15cm^(3)` of sodium hydroxide solution whose normality is

10cm^(3) of 0.1 N monobasic acid requires 15cm^(3) of sodium hydroxide solution whose normality is

In a titration 20 cm^(3) of 0.1 N oxalic acid solution requires 20 cm^(3) of sodium hydroxide for complete neutralization. The mass of sodium hydroxide in 250 cm^(3) solution is

Battery acid (H_(2)SO_(4)) has density 1.285 g cm^(-3) , 10.0 cm^(3) of this acid is diluted to 1L . 25.0 cm^(3) of this diluted solution requires 25.0 cm^(3) of 0.1 N sodium hydroxide solution for neutralization. The percentage of sulphuric acid by mass in the battery acid is :

0.99 g of an acid was dissolved in water and the solution made up to 200 cm^(3) , 20 cm^(3) of this solution required 15 cm^(3) of 0.105 N sodium hydroxide solution for complete neutralization. Find the equivalent mass of the acid.
