To prepare the HCl solution if 1% m/v HCL was available, take 2.5ml of the stock solution and makeup to mark with 7.5 ml of water.

What is HCl?

HCl is hydrochloric acid, and it is a highly reactive and strong acid.

Given, the dilution formula

C₁V₁= C₂V₂

C₁ = initial concentration

V₁ = initial volume

C₂ = Final concentration

V₂ = final volume

The values are

C₁ = 1% m/v

V₁ = ?

C₂ = 0.25% m/v

V₂ =  10 ml

V₁  = C₂V₂/C₁

V₁  = 0.25% m/v ×  10 ml /1% m/v

V₁  = 2.5 ml

Thus, the amount of HCl is 2.5ml of the stock solution. The amount of water is 7.5 ml of water.
