JEE MAIN - Chemistry (2002 - No. 5)
1 M NaCL and 1 M HCL are present in an aqueous solution. The solution is
not a buffer solution with pH < 7
not a buffer solution with pH > 7
a buffer solution with pH < 7
a buffer solution with pH > 7
Vysvetlenie
NOTE : A buffer is a solution of weak acid and its salt with strong base and vice versa.
$$HCL$$ is strong acid and $$NaCL$$ is its salt with strong base.
$$pH$$ is less than $$7$$ due to $$HCL$$.
$$HCL$$ is strong acid and $$NaCL$$ is its salt with strong base.
$$pH$$ is less than $$7$$ due to $$HCL$$.
