Explanation / Answer

1. Answer: pH paper is quantitative: The difference between pH Paper and litmus paper is that

pH Paper can give the pH value of the solution whereas litmus paper can determine whether a solution is acidic or basic.

2. Answer: pH meter is quantitative because it shows the exact pH of the solution.

3. Answer: changes colour according to the acidity or basicity of the solution

4 Answer: NaOH has lowest H+ concentration (though NaOH is basic in nature, so [H+] = 10-pH)

5. Answer: NaOH is basic though it produces OH- ion
