200 ml 0.6 N H₂SO₄ and 100 ml of 0.3N HCl are mixed together. Acidic normality of the resultant solution is:

A mixture containing Cd²⁺ and Ni²⁺ can be separated for identification by:

Which one of the following sulphides is only completely precipitated when the acidic solution is made dilute?

25 ml of a solution of Na₂CO₃ having a specific gravity of 1.25 required 32.9 ml of a solution of HCl containing 109.5grams of the acid per litre for complete neutralization. Calculate the volume of 0.84 N – H₂SO₄ that will be completely neutralized by 125 grams of the Na₂CO₃ solution:

In order to prepare one litre normal solution of KMnO₄, how many gm of KMnO₄ are required, if the solution is to be used in acid medium for oxidation:

How many grams of NaOH are equivalent to 100 ml of 0.1 N oxalic acid?

0.126g of an acid requires 20 ml of 0.1N NaOH for complete neutralization. The equivalent weight of the acid is:

0.16 gm of a dibasic acid required 25 ml of decinormal NaOH solution for complete neutralization. The molecular weight of the acid is:

0.1914g of an organic acid is dissolved in approx. 20 ml of water. 25 ml of 0.12 N NaOH required for the complete neutralization of the acid solution. The equivalent weight of the acid is:

1 gm of hydrogen is found to combine with 80 gms of bromine. 1 gm of calcium (valency 2) combines with 4 gms of bromine. The equivalent weight of calcium is:
