Expert Answer

Step 1

Hello. Since your question has multiple sub-parts, we will solve first three sub-parts for you. If you want remaining sub-parts to be solved, then please resubmit the whole question and specify those sub-parts you want us to solve.

Step 2

The HCl, being strong electrolyte, completely dissociate in the solution and give the hydrogen ion. The concentration of H+ ion is equal to 1.0×10-5 M. The pH for 1.0×10-5 M HCl solution is calculated as shown below. The pH for 1.0×10-5 M HCl solution is 5.
