Question

Rx: hydrochloric acid 2 percent solution 500 ml. your stock solution of hydrochloric acid is 10 percent. how much of the stock solution is required to prepare the order?

Answer 1

100 ml

100 ml of the stock solution is required to prepare the order.

We know that C1V1 = C2V2

where C1= 2%

V1 = 500ml

C2= 10%

V2 = ?

V2 = C1V1 / C2

     = 500 * 2% / 10%

     =100

V2 = 100 ml

What is meant by stock solution?

• A stock solution is a sizable amount of a typical reagent in a standardized concentration, like sodium hydroxide or hydrochloric acid.
• This phrase is frequently used in analytical chemistry while doing operations like titrations where it's crucial to employ precise solution concentrations.

What distinguishes a standard solution from a stock solution?

• The main distinction between stock solution and standard solution is that the former is a highly concentrated solution while the later is a solution whose concentration is precisely known.
• Because standard solutions frequently arrive as stock solutions, the phrases "stock solution" and "standard solution" are connected.
