A 25mL HCl solution containing 3.65g HCl/L is neutralized by 50mL of NaOH solution. Again, 25mL of an `H_(2)SO_(4)` solution of unknow strenght. The normally of the `H_(2)SO_(4)` solution is :

12 g of H_(2)SO_(4) are dissolved in water to make 1200 ml of solution. The normality of the solution is

If 100 ml of a solution contains 10 g of H_(2)SO_(4) , normality of the solution is

0.7g of (NH_(4))_(2)SO_(4) sample was boiled with 100mL of 0.2 N NaOH solution was diluted to 250 ml. 25mL of this solution was neutralised using 10mL of a 0.1 N H_(2)SO_(4) solution. The percentage purity of the (NH_(4))_(2)SO_(4) sample is :

0.7g of (NH_(4))_(2)SO_(4) sample was boiled with 100mL of 0.2 N NaOH solution was diluted to 250 ml. 25mL of this solution was neutralised using 10mL of a 0.1 N H_(2)SO_(4) solution. The percentage purity of the (NH_(4))_(2)SO_(4) sample is :

10 mL of a H_(2)SO_(4) solution is diluted to 100 mL. 25 mL of this diluted solution is mixed with 50 mL of 0.5 N NaOH solution. The resulting solution requires 0.265 g Na_(2)CO_(3) for complete neutralization. The normality of original H_(2)SO_(4) solution is :

0.80g of impure (NH_(4))_(2) SO_(4) was boiled with 100mL of a 0.2N NaOH solution till all the NH_3 (g) evolved. the remaining solution was diluted to 250 mL . 25 mL of this solution was neutralized using 5mL of a 0.2N H_(2)SO_(4) solution. The percentage purity of the (NH_(4))_(2)SO_(4) sample is:
