10g" impure NaOH is completely neutralised by "1000ml" of "(1)/(10)NHCl" .Calculate the percentage purity of the impure Nao "

10 g impure NaOH is completely neutralised by 1000 ml of (1)/(10)N HCl . Calculate the percentage purity of the impure NaOH.

10 g impure NaOH is completely neutralised by 1000 ml of (1)/(10)N HCl . Calculate the percentage purity of the impure NaOH.

An impure sample of (NH_(4))_(2)SO_(4) is supplied to a laboratory. 3.6g of the supplied (NH_(4))_(2)SO_(4) salt on heating with NaOH forms NH_(3) gas. 100 mL of 0.5(N)H_(2)SO_(4) is required for the complete neutralisation of the liberated NH_(3) gas. calculate the percentage purity of the impure sample. let us assume, the impurity of the sample is insoluble in NaOH.

3.0 g of impure Na_2CO_3 is dissolved in water and the solution is made up to 250 mL . To 50 " mL of " this solution, 50 " mL of " 0.1 N HCL is added and the mixture, after shaking well, required 10 " mL of " 0.16 N NaOH solution for cojmplete neutralisation. Calculate the percentage purity of the sample of Na_2CO_3 .

150 mL of N/10 HCI are required to react completely with 1.0 g of a sample of lime stone ( CaCO_3 ). Calculate the percentage purity of the sample.

0.70g mixture of (NH_(4))_(2)SO_(4) was boiled with 100 ml of 0.2 N NaOH solution will all the NH_(3)(g) evolved and get dissolved to 250 mL and 10 mL of this solution was neutralised by using 10 mL of a 0.1 N H_(2)SO_(4) . The percentage purity of the (NH_(4))SO_(4) was boiled with 100 ml of 0.2 N NaOH solution till all the NH_(3)(g) evolved and get dissolved to 250 mL and 10 mL of this solution was neutralised by using 10 mL of a 0.1 N H_(2)SO_(4) solution. the percentage purity of the (NH_(4))_(2)SO_(4) sample is-

10ml of 1 M H_(2)SO_(4) will completely neutralise
