Answer 2

Answer: ph paper is an acid-base indicator that is used to identify the acidic or basic nature of a substance.

→ If ph no. is less than 7, then the substance has acidic nature

→ If ph no. is more than 7, then the substance has basic nature

→ If ph paper is equal to 7, then the substance is neutral

★ so, a solution with less number of ph will be acidic and would contain H+ ions co

hence solution with ph number 4 has more H+ ions concentration.
