Question

In a solution of boric acid, if the ratio of sodium borate to boric acid is 1.78 and the concentration of sodium borate is 0.75 moles then find out the concentration of boric acid?

Answer 1

if the ratio of sodium borate to boric acid is 1.78

the concentration of sodium borate is 0.75 moles 

Ratio = 178:100

Therefore:

(178/100)(0.75)

= 1.335 M

Therefore the concentration of boric acid = 1.335M
