Question

4 solution a b c d with PH values 8 13 4 2 respectively (a) which which of them is most acidic (b) arranged them in the decreasing order of their oh- ion construction

Answer 1

Answer:

In chemistry, pH (/piːˈeɪtʃ/, denoting 'potential of hydrogen' or 'power of hydrogen'[1]) is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions (solutions with higher concentrations of H+ ions) are measured to have lower pH values than basic or alkaline solutions.
