Question

18.1A Which member of each pair is the stronger acid or base?

a) HCIO or HCIO3

b) HCI or CH3COOH

HCl is the strongest

And

c) NaOH or CH3NH2

Answer 1

Answer:

$(a)=HClO_{3}$,    $(b)=HCl$,      $(c)=NaOH$

Explanation:

$(a)=HClO_{3}$    

$HClO_{3}$  is more acidic then $HClO$  due to the $ClO^{-}$ is strongest base from the$ClO_{3}^{-}$ so $HClO_{3}$   is more acidic then the $HClO$.

$(b)=HCl$  

$HCl$  is more acidic from the $CH_{3}COOH$ because  $CH_{3}COOH$ is weak acid and $HCl$ is strongest acid .

$(c)=NaOH$

$NaOH$ is strongest base from the $CH_{3}NH_{2}$ because $NaOH$ break down in form of $H^{+}$ and $OH^{-}$.$OH^{-}$ is strongest basic in nature.$CH_{3}NH_{2}$ break down in two parts $H^{+}$ and $CH_{3}NH^{-}$.$OH^{-}$is more basic from the $CH_{3}NH^{-}$ so $NaOH$ is more basic from the $CH_{3}NH_{2}$.
