There are two solutions A and B such that Solution A has pH of 6.5 and Solution B has pH of 8.6. Which of the following is/are correct in this context?
- Solution A has higher H+ concentration and will turn blue litmus red.
- Solution B has higher H+ concentration and will turn red litmus blue.
- Solution A has higher OH– concentration and will turn blue litmus red.
- Solution B has higher OH– concentration and will turn red litmus blue.
Select the correct option from codes given below:
Only 1 & 4 are correct statements.
A strongly basic (or alkaline) solution has a high concentration of OH- ions and few H+ ions, whereas a strong acid has higher concentration of H+ ions and lower OH- ions. Acids turn blue litmus red and bases turns red litmus blue.
