A quantity of ammonium chloride was heated with 100 mL of 0.8 N NaOH solution till the reaction was complete. The excess of NaOH was neutralised with 12.5 mL of `0.75N H_(2)SO_(4)`. Calculate the quantity of ammonium chloride.

Some amount of NH_4 CI was boiled with 50ml of 0.75 N NaOH solution till the reaction was complete. After the completion of the reaction 10 ml of 0.75 N H_2 SO_4 was required for the neutralization of the remaining NaOH . The amount of NH_4 CI taken was:

Heat liberated when 100 mL of 1 N NaOH is neutralised by 300 mL of 1 N HCl

Heat liberated when 100 mL of 1N NaOH is neutralised by 300 ml of 1N HCl

100 mL of mixture of NaOH and Na_(2)SO_(4) is neutralised by 10 mL of 0.5 M H_(2) SO_(4) . Hence,the amount of NaOH in 100 mL solution is

100 ml of 0.1 N NaOH is mixed with 50 ml of 0.1 N H_2SO_4 . The pH of the resulting solution is
