Question

Consider the pH value of the following acidic samples. The decreasing order of their $\mathrm{H}^{+}$ion concentration is\

Professor PC Thomas Classes · Answer

(c) : The concentration of $\mathrm{H}^{+}$ions increases with increase in acidic strength of any acid. Also, as pH value increases, acidity decreases. $$ \mathrm{pH} \propto \frac{1}{	ext { Acidity }} \propto \frac{1}{	ext { Concentration of } \mathrm{H}^{+}} $$ So, decreasing order of $\mathrm{H}^{+}$ion concentration is : Gastric juice > Lemon juice > Dilute acetic acid > Vinegar $$ 2>1>4>3 $$
