Vidyadip · Accepted Answer

pH of solution A	pH of solution B	$\left[ H _3 O ^{+}\right]$in solution A (In molarity)	$\left[ H _3 O ^{+}\right]$in solution B (In molarity)	How much less is the pH of solution A than PH of solution B?	How many times is the concentration of $H _3 O ^{+}$ in solution A more than that of concentration in solution B ?
5	6	$10^{-5}$	$10^{-6}$	1	$10^1=10$
3	5	$10^{-3}$	$10^{-5}$	2	$10^2=100$
2	5	$10^{-2}$	$10^{-5}$	3	$10^3=1000$
2	6	$10^{-2}$	$10^{-6}$	4	$10^4=10,000$
1	6	$10^{-1}$	$10^{-6}$	5	$10^5=1,00,000$
2	4.5	$10^{-2}$	$10^{-4.5}$	2.5	$10^{2.5}=\operatorname{antillog}(2.5)=316.2$
1.9	5.3	$10^{-1.9}$	$10^{-5.3}$	3.4	$10^{3.4}=\operatorname{antilog}(3.4)=2152$
