A student compares two buffers and then adds the same small amount of strong base to each. Buffer A:

\text{HNO}_2/\text{NO}_2^-

with

0.40\,\text{M}

\text{HNO}_2

and

0.40\,\text{M}

\text{NaNO}_2

. Buffer B:

\text{HNO}_2/\text{NO}_2^-

with

0.10\,\text{M}

\text{HNO}_2

and

0.70\,\text{M}

\text{NaNO}_2

. Which buffer will show the smaller pH change?
