Question

If 20mL of 0.5N salt solution is diluted to 1L, What is the new concentration?

Answer 1

Ответ:

Here, Let M

1

(molarity H

)=2M, V

1

(volume of H

2

SO

)=20ml=0.02L, V

2

(volume of solution)=1L and M

2

(molarity of resulting solution)=?

Therefore, M

1

×V

=M

2

×V

=0.04M

Normality=M

×n , here n is number of H

+

ions an acid can donate

Normality=0.04×2=0.08N
