The pH of a monoprotic weak acid which is 80 percent ionised with a strentght of 0.05m is 1.39
What is pH ?
A scale called pH , which traditionally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are recorded for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions. The concentration of hydrogen ions in the solution is shown inversely by the pH scale, which is logarithmic.
pH + pOH = 14
[H + ]=0.05×0.80=0.04M
Now, Here, pH=−log[H + ]=−log0.04=1.39
