Question

100 ml of 0.15 M HCI is mixed with 100 ml of 0.005 M HCI. What is the pH of the
resulting solution
2.5
2) 1,5
3) 2
4) 1​

Answer 1

option d. ur ph value is 1

Answer 2

Answer:

2.5

Explanation:

Resultant Molarity = V1+V2M1V1+M2V2

                             =200(0.15)×(100)+(0.005)×100

                             =200100[0.155]=20.155=0.785

⇒pH=−log(H+)

             =−log(0.785)=2.5
