The volume of `0.1 N` dibasic acid sufficient to neutralize 1g of a base that furnishes `0.04` mole of `OH^-` in aqueous solution is :

Mole fraction of the solute in a 1.0 molal aqueous solution is:

The mole fraction of solvent in 0.1 molal aqueous solution is

How much volume of 0.1N NaOH will neutralize 10mL of 0.1N phosphoric acid

If 20 mL of 0.4 N NaOH solution completely neutralises 40 mL of a dibasic acid, the molarity of the acid solution is :

The volume of 0.1 M Ca (OH)_(2) needed for the neutralization of 40 ml of 0.05 M oxalic acid is

Given that, heat of neutralisation of strong acid and strong base is 57.1 kJ. Calculate the heat produced when 0.25 mole of HCl is neutralised with 0.25 mole of NaO in aqueous solution:
