Question

if 98 gm h2so4 dissolved in 50 l solution .calculate pH​

Answer 1

Answer:

Explanation:

Molarity of H  

2

​  

SO  

4

​  

=  

98×500

9.8×1000

​  

=0.2M

As H  

2

​  

SO  

4

​  

 is strong acid so it dissociates completely to give H  

+

 ions.

H  

2

​  

SO  

4

​  

→2H  

+

+SO  

4

2−

​  

 

0.2

                   0.2×2     0.2

[H  

+

]=2×0.2=0.4M

pH=−log([H  

+

])=0.3979
