How Do We Dilute Concentrated Hydrochloric Acid to Give 10% HCl?

Answer:

The solubility of the solute determines the strength of a solution which refers to the ability of a solute to dissolve in a solvent. The concentration of a solution can be classified into the following classes based on the strength of the solution.

  1. Diluted solution
  2. Concentrated solution 

To make a 10% HCl solution, mix water, and Conc. hydrochloric acid (HCl) in a 10:1 ratio, which means that for every 100 mL of water, you’ll need 10 mL of HCl to reach the necessary concentration. 

In a beaker, get the right amount of deionized (DI) water, and in another, get the right amount of HCl. Pour all 10 ml of the HCl into the water slowly. Allow the acid to mix for a minute or two before using it, or swirl gently with a clean glass rod before rinsing it in DI water. Make sure to add acid to water and not water to acid.

Need to dilute acids: 

  • Sometimes we need to dilute the concentrated acids according to the requirement of a chemical reaction or experiment
  • Dilution reduces the amount of dissolved material in a solution. It has no effect on the acid’s strength or reactivity but reduces the acid content of the solution you’re working with
  • The matching of the amounts of reactants to one another in a chemical reaction is important so that each reactant is totally consumed
  • When working with concentrated storage supplies of acids, you must additionally dilute them
