The solution that is made by mixing appropriate amount of a weak acid and salt is called
1 Basic buffer
2 Acidic buffer
3 Neutral buffer
4 Both (a) and (b)
Explanation:
A buffer solution is one which resists changes in $\mathrm{pH}$ when small quantities of an acid or an alkali are added to it. Acid buffer has acidic $\mathrm{pH}$. As the name suggests, these solutions are used to maintain acidic environments. An acidic buffer solution is simply one which has a $\mathrm{pH}$ less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt.

An acidic buffer solution could be prepared by mixing the solutions of the following
1 Sodium acetate and acetic acid
2 Ammonium sulphate and sulfuric acid
3 Ammonium chloride and ammonium hydroxide
4 Sodium chloride and hydrochloric acid
Explanation:
Buffer solution:- A buffer solution that can resist $\mathrm{pH}$ change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the $\mathrm{pH}$ of the solution relatively stable. Acidic buffer solution $=$ Weak acid + Salt of strong base

$\mathrm{H}_2+\mathrm{CO}+$ alkene $\stackrel{\text { catalyst }}{\longrightarrow} 1^{\circ}$ alcohol What is the stable intermediate and the nature of the reaction?
1 acid reduction
2 aldehyde, oxidation
3 aldehyde, reduction
4 alcohol, oxidation
Explanation:
Alkene combine with carbon monoxide and hydrogen in the presence of octa carbonyl dicobalt as catalyst under high temperature and pressure to form aldehydes. $\mathrm{H}_2+\mathrm{CO}+\mathrm{CH}_2=\mathrm{CH}_2 \rightarrow \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH}$ - Stable intermediate aldehyde are from - Reduction Reaction.

Which one of the following in NOT a buffer solution?
Buffer solution contains weak base + salt of weak base with strong acid or weak acid +salt of weak acid with a strong base. In option (d) the used is $\mathrm{HCIO}_4$ which is strong base . hence, it is not an example of buffer solution.
