Question

What is the Hydrogen ion concentration in mol/L in a
solution of pH = 5.4 ​

Answer 1

Answer:

68×10−6

Explanation:

Answer 2

Answer :

$3.98 \times {10}^{ - 6} \: \: mol {L}^{ - 1}$

Explanation :

$pH = - log{[ {H}^{ + } ]} \\ 5.4 = - log [{H}^{ + }] \\ [{H}^{ + }] = antilog( - 5.4) \\ \\ [{H}^{ + } ] = 3.98 \times {10}^{ - 6} mol/L$
