Question

Which of the following is not an acidic salt?
(A) $CuS{O_4}$
(B) $N{a_2}C{O_3}$
(C) $ZnS{O_4}$
(D) $N{H_4}N{O_3}$ ​

Answer 1

Any salt that can replaceable hydrogen particles known as acidic Salt. The fluid arrangement of acidic salt turns blue litmus red. Consequently, the watery arrangements of salt are acidic in nature. In the acids, the hydrogen iota that are joined to the oxygen particles are known as replaceable hydrogen iotas. Hydrogen iotas connected to Phosphorus straightforwardly are not replaceable

Complete step by step answer
Interestingly, a powerless acid just incompletely separates and at harmony both the acid and the form base are in arrangement. Instances of solid acids are hydrochloric acid, hydroiodic acid, hydrobromic acid, perchloric acid, nitric acid and sulfuric acid. In water each of these basically ionizes $100\%$ . In water each of these basically ionizes $100\%$ .
Sodium carbonate $N{a_2}C{O_3}$ is certainly not an acidic salt. It is a fundamental salt. It is a salt of the solid base NaOH with feeble acid ${H_2}C{O_3}$ . Watery sodium bicarbonate arrangement has pH more than 7.

Hence, option B is correct.

Additional Information
The strength of an acid alludes to its capacity or propensity to lose a proton. A solid acid is one that totally separates in water; at the end of the day, one mole of a solid acid $HA$ breaks down in water yielding one mole of ${H^ + }$ and one mole of the form base, ${A^ - }$ , and none of the protonated acid $HA$ . The more grounded acid is, the more effectively it loses a proton, ${H^ + }$ . Two key factors that add to the simplicity of deprotonation are the extremity of the $H - A$ bond and the size of molecule $A$ , which decides the strength of the $H - A$ bond.

Note
The first classification of acids are the proton contributors, or Bronsted–Lowry acids. In the exceptional instance of watery arrangements, proton benefactors structure the hydronium particle and are known as Arrhenius acids. Bronsted and Lowry summed up the Arrhenius hypothesis to incorporate non-fluid solvents. A Bronsted or Arrhenius corrosive ordinarily contains a hydrogen iota attached to a synthetic structure that is still enthusiastically ideal after loss of ${H^ + }$ .
