Question

What ALWAYS distinguishes a weak acid from a strong acid? a. A weak acid doesn't react much in water; strong acids completely react. b. A weak acid is more dilute than a strong acid. c. A weak acid has a higher pH than a strong acid. d. Statements a and c are both characteristics that distinguish weak acids from strong acids. e. Statements a, b, and c are all characteristics that distinguish weak acids from strong acids. What ALWAYS distinguishes a weak base from a strong base? A weak base doesn't react much in water; strong bases completely react. A weak base is more dilute than a strong base. A weak base has higher pH than a strong base. Statements a and c are both characteristics that distinguish weak bases from strong bases. Statements a, b, and c are all characteristics that distinguish weak bases from strong bases.

Explanation / Answer

(1)

(a) Weak acid doesnot dissociate in water completely ,where as strong acid will dissociates completely gives out hydrogen ions.

(b) weak acid is more dilute than strong acid . This is FALSE

(c) pH of Strong acid is low and weak acid has more pH(<7)

So, correct answer is option (d)

(2)

(a) Weak base doesnot dissociate in water completely ,where as strong base will dissociates completely gives out OH ions.

(b) weak base is more dilute than strong base . This is FALSE

(c) pH of Strong base is high and weak base has less

So, correct answer is option (a)
