Question

Baking soda is
A. Basic salt
B. Acidic salt
C. Complex salt
D. Double salt

Answer 1

Hint: A cation (base) and an anion (charge) make up the ionic compound known as salt (acid). It is the primary mineral component of seawater and is abundant there. Sodium bicarbonate, often known as baking soda or $NaHC{O_3}$, is a chemical compound that is created when a strong base and a weak acid combine.

Complete Step by Step Solution:
The salt is referred to as acidic salt if it has replaceable hydrogen atoms in its composition. The litmus tends to turn red from blue when the acidic salt is dissolved in water. For acidic salts, the pH, hydrogen power, or hydrogen potential is less than 7. This is due to the acidic protons that were not neutralised during the neutralisation reaction that created salt. The diprotic or polyprotic acid is often partially neutralised to create the acidic salt. They include another cation and ionizable hydrogen ions.

Baking soda, sodium hydrogen carbonate, or sodium bicarbonate are the products of the reaction between a sodium hydroxide solution and lime water or a solution containing carbon dioxide dissolved in water. When sodium bicarbonate is dissolved in water, the sodium cations and hydroxide anions are released, which causes the solution to become basic.

On the other hand, the pH of the solution is unaffected by the weak carbonic acid.
Since sodium bicarbonate, or baking soda, contains one replaceable hydrogen atom and reacts with bases, it is an acidic salt. When sodium bicarbonate is dissolved in water, it produces a basic solution because the anion in the salt undergoes hydrolysis and releases free OH ions.
Hence option B is correct.

Note: By noting the formulas and evaluating the potency of the parent acid and base that can be used to create the salt, one can estimate the salt's acid or basic properties. Hydrogen gas is created when metals and acids react. When these compounds are dissolved in water, hydroxide ions are released.
