How do you make diluted HCl?

Concentrated hydrochloric acid (HCl) is a hazardous chemical a strong inorganic acid which is highly corrosive. To prepare 10% HCl solution, Take water and HCl in ratio 10:1 which means that if you take 100 mL of water, you require 10mL of HCl to achieve the desired concentration.

How do you make 0 1N HCl?

Mix one mole (36.5gram) of HCL in 100mL of water or else you can add 0.1 mole (3.65 gram) of HCL in 1000mL or 1 L of water.

What is pH of 0.1 N HCl?

This makes the solution neutralization thus pH of the solution becomes equal to 7. And coming to the last option D, 500 ml of HCl of pH is equal to 1. Now we will calculate the pH of 20 ml of 0.1 N HCl. Option D gives that pH value of the solution is 1.
