Question

A 0.1 m solution of which salt is the most basic? (a) nano3 (b) naclo4 (c) nahso4 (d) nahco

Answer 1

The most basic of the given salts is option (a) NaNO3

Step-by-step explanation:

The most basic of the given salts is option (a) NaNO3.

In order to determine whether a salt solution is acidic, basic, or neutral, we need to consider the hydrolysis of the salt. Hydrolysis occurs when a salt reacts with water to produce acidic or basic species.

NaNO3 can be written as Na+ + NO3-. Since Na+ is the conjugate base of a strong acid (NaOH) and NO3- is the conjugate acid of a weak base (HNO3), the solution of NaNO3 will be basic.

Answer 2

Answer is: d) NaHCO₃ - sodium hydrogen carbonate or sodium bicarbonate.
It is because other salt are made in reaction between strong base and strong acid and sodium hydrogen carbonate is made from strong base (sodium hydroxide) and weak acid (carbonic acid).
Sodium bicarbonate is an aqueous solution is used for cases of acidosis.
