Question

What is the recommended way of preparing 100ml of 0.02M from 2M NaOH in the laboratory?​

Answer 1

The recommended way of preparing 100ml of 0.02 M from 2M NaOH in the laboratory is to obey the equation V1S1=V2S2.

Step-by-step explanation:

According to the given question

V2=100ml

S2=0.02M

S1= 2M

Then V1=?

We all know that V1S1=V2S2

or V1=V2×S2÷S1

or V1= 100×0.02÷2

or V1 =1 ml

It can be concluded that 1ml of 2M NaOH solution and 99 ml distilled water should be mixed to prepare 100ml of 0.02 M NaOH solution.
