Question

Which of the following is a Buffer solution? (A)  NaOH+NaCl  (B)  KOH+KNO3  (C)  CH3COOH+CH3COONa  (D) all of the above

Tardigrade Admin · Accepted Answer

Buffer solution is obtained when a solution is prepared of either (weak acid +its salt with strong base) or (weak base + it salt with strong acid). Hence, CH3COOH+CH3COONa is a Buffer solution.

Q. Which of the following is a Buffer solution?

$N a O H + N a Cl$

$K O H + K N O_{3}$

$C H_{3} COO H + C H_{3} COON a$

all of the above

Buffer solution is obtained when a solution is prepared of either (weak acid +its salt with strong base) or (weak base + it salt with strong acid). Hence, $C H_{3} COO H + C H_{3} COON a$ is a Buffer solution.
