According to the $Br\o nsted-Lowry$ theory,water is a/an:

$A$ base is dissolved in water to yield a solution with a hydroxide ion concentration of $0.05 \ mol \ L^{-1}$. The solution is

When a strong acid,strong base,or their salt are dissolved in water,they are completely ionised. If a strong acid is added to a strong base,$H^{+}$ ions from the former combine with $OH^{-}$ ions of the latter forming water. The formation of each water molecule liberates a certain quantity of energy and the reaction is exothermic. The heat liberated when one mole of water is formed by combining hydrochloric acid and sodium hydroxide is $13.7 \, kcal$. The heat liberated when one mole of water is formed by combining sulphuric acid and sodium hydroxide is......$kcal$

Match the given ionisation constant values with the corresponding acids.

$A$. $HI$	$(i)$ $3.2 \times 10^9$
$B$. $HF$	$(ii)$ $3.5 \times 10^{-4}$
$C$. $HCl$	$(iii)$ $1.3 \times 10^6$
$D$. $HBr$	$(iv)$ $1.0 \times 10^9$

The correct match is:

Give the conjugate acid and conjugate base of the following:
$(i)$ $(CH_3)_2NH$
$(ii)$ $HPO_4^{2-}$
$(iii)$ $HS^{-}$

The conjugate base of $NH_3$ is
