Question

What is the hydrogen ion concentration, [h ], in a 0.043 m solution of sulfuric acid (h2so4)?

Answer 1

The hydrogen ion concentration for H2SO4 is 0.086.

For strong acids such as H2SO4 (sulphuric acid), the degree of dissociation is 100%. 

Since H2SO4 is dibasic ie., gives out 2 hydrogen atoms on dissociation, the hydrogen ion concentration for it is given by the formula:

[H+] = 2 x C
[H+] = 2 x 0.043
[H+] = 0.086

Answer 2

0.086 is your answer. ....
