Acids "A" and "B" were taken in two beakers. Acid "A" ionizes partially in water while acid
"B" ionizes completely. On this basis, tell:
(a) Which among "A" and "B" is strong acid and which is weak?
(b) What is a weak acid?
(c) What is a strong acid?
(d) Give examples of both strong and weak acids.

a) Acid 'A' is weak acid while Acid 'B' is strong.To know the reason see following answers.
b) Weak acids are those that partially ionizes in water to give H⁺ ions.Here Acid 'A' ionizes partially hence it is weak.
c) Those acids that ionize completely into H⁺ ions in water are called strong acids.Acid 'B' ionizes completely hence it is strong.
d) Strong acids -- HCl , H₂SO₄, HNO₃
Weak acids -- CH₃COOH , H₂C₂O₄
Hope This Helps You!

Hey there,(a) acid 'A' is a weak acid. weak acid ionizes prtially in aq. solution. they are less harmful to us.
acid 'B' is a strong acid. strong acid ionizes completely in aq. solution. as they are strong, they are more harmful to us.
(b) weak acid ionizes completely in aq. solution. their pH range is from 5-7.
(c) strong acids ionizes partially in water. their pH range is from 1-4.
(d) examples of
weak acid:- CH₃COOH, CH₃OH.
srtong acid:- HCl, HNO₃, H₂SO₄.
hope it helps..
