Hydrogen ion concentration in mol/L in a solution of pH = 5.4 will be:

Solution & Step-by-step Explanation

By definition, pH = - lo g [H^{+}] . 5.4 = - lo g [H^{+}] lo g [H^{+}] = - 5.4 = - 6 + 0.6 Taking antilog: [H^{+}] = antilog (0.6) \times 1 0^{- 6} Since lo g 4 \approx 0.6, the value is approximately 4 \times 1 0^{- 6} .More precisely, [H^{+}] = 3.98 \times 1 0^{- 6} mol/L .

Try it yourself before checking the explanation above.

Hydrogen ion concentration in mol/L in a solution of pH = 5.4 will be:

3.98 \times 1 0^{- 8}

3.88 \times 1 0^{- 6}

3.68 \times 1 0^{- 6}

3.98 \times 1 0^{- 6}
