Question

100 ml of 0.015 M HCL solution is mixed with 100 ml of 0.005 M HCI.

What is the pH of the resultant solution
1 )2.5 2 ) 1.5 3 ) 2.0 4 ) 1.0

Answer 1

Answer:

Option 1) is the approximate answer.

Explanation:

Refer attachment for explanation!!!

Answer 2

Answer:

1.5 (B)

Explanation:

we have to find the pH of the resultant solution so we have to find the concentration of resultant solution the inlo thing which remain constant is the no of moles

no of moles = vol *conc

                        100*0.015=15

                        100*0.005=0.5

now the conc of soln= no of males /vol

                                 =15+.5/100+100=0.0775

now pH = -log(.0775)=1.5
