Question

how to prepare 100 ml 1N HCl

Answer 1

Answer:

Explanation:

1N HCL - add 36.46 gm of HCL in 1 litre of water (Molar mass of HCL = 36.46 g/mole)

36.46 g of HCL is equivalent to 30.67 ml of HCL ( Volume = Mass/Density = 36.46/1.19 = 30.67)

Density of HCL is = 1.19 g/ml

Percent Concentration of Most Conc HCL is = 37.5 %

30.67 ml of HCL is equal to = (30.67)*(100/37.5) = 81.8 ml HCL

Hence to prepare 1N HCL - add 81.8 ml of HCL in 1000 ml of Water.

To make 0.1 N HCL - add 8.18 ml HCL in 1000 ml of water
