whose solution labelled as p, q, r and s have PH value 1,9,3 and 13 respectively. which of the following statement about the given solution is incorrect?
(A) solution p has higher concentration of hydrogen ions then solution r.
(B) solution q has lower concentration of hydroxyl ions then solution R.
(C) solution p and q will turn red litmus solution blue.
(D) solution p is highly acidic while solution q is weekly basic
Answers
Answer:
A and D statement are correct.......
B and C are incorrect .....
Answer:
The correct options are b and c.
Explanation:
Acid are the chemical substances that are sour in taste and turn blue litmus paper into red. Their pH ranges from 0 - 6.9. whereas bases are bitter in taste and they turn red litmus paper into blue. Their pH value ranges from 7.01 - 14. Higher is the pH more is the concentration of OH⁻ (hydroxyl ion) and less is the concentration of H⁺ ion. So the solution having pH from 0 - 6.9 would have more concentration of H⁺ ion and very less concentration of OH⁻. Similarly, the solution having pH 7.01 - 14 would have more concentration of OH⁻ ion and less concentration of H⁺ ion. So, solution p has the highest concentration of H⁺ ion and s has the highest concentration of OH⁻ ion. And p and r are acidic solutions that turn blue litmus into red whereas q and s are basic solutions which turn blue litmus into red. Hence, the incorrect statements are b and c.
