When the pH of the solution decreases, its hydrogen ion concentration
increases
decreases
nothing can be said
remains same
pH = - log[H+] i.e. lower the pH higher the concentration of [H+]
When pH decreases, the hydrogen ion concentration increases.
pH is decreased, when hydrogen ion concentration increases.
On increasing the resistance in a circuit, the current in it :
(a) decreases (b) increases
(c) remains unchanged (d) nothing can be said.
