A sample of pure sodium carbonate 0.318g is dissolved in water and litrated with HCI solution. A volume of 60mL is required to reach the methly orange end point. Calculate the molarity of the acid.

0.075 g of a monobasic acid required 10 mL of N//12 NaOH solution for complete neutralisation. Calculate the molecular mass of the acid

1.26 g of hydrated oxalic acid was dissolved in water to prepare 250 ml of solution. Calculate molarity of solution

A sample of sodium carbonate contains impurity of sodium sulphate. 1.25 g of this sample are dissolved in water and volume made up to 250 mL. 25 mL of this solution neutralise 20 mL of N/10 sulphuric acid. Calculate the percentage of sodium carbonate in the sample.

Benzoic acid is an organic compound. Its crude sample can be purified by crystallisation from hot water. What characeteristic difference in the properties of benzoic acid and the impurity make this process of purification suitable ?

0.126 g of acid required 20 mL of 0.1 N NaOH for complete neutralisation. The equivalent mass of an acid is

1g of a monobasic acid dissolved in 200g of water lowers the freezing point by 0.186^(@)C . On the other hand when 1g of the same acid is dissolved in water so as to make the solution 200mL , this solution requires 125mL of 0.1 N NaOH for complete neutralization. Calculate % dissociation of acid ? (K_(f)=1.86(K-kg)/("mol"))

A 1.025 g sample containing a weak acid HX (mol. Mass=82) is dissolved in 60 mL. water and titrated with 0.25 M NaOH. When half of the acid was neutralised the pH was found to be 5.0 and at the equivalence point the pH is 9.0. Calculate mass precentage of HX in sample : a. 50% b. 75% c. 80% d.None
