Question

Aqueous solution of which salt will not contain ions with the electronic configuration of $1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}$?
A. $NaF$
B. $KBr$
C. $NaCl$
D. $Ca{{I}_{2}}$

Answer 1

An aqueous solution is one in which the dissolvable is fluid water. That is, solute (disintegrated) ions and atoms are encircled by water particles and joined into the organization of securities inside the water. The disintegrated species at that point spread all through the water.

Complete Step by step answer: It is neutral because the Na and F atoms are transferring their valence electrons in order to become stable. This results in an overall stable atom. If we were to identify the individual charges of said atoms, Na would have a positive charge, and $F$a negative charge. $NaF$ is an ionic compound. . Ionic compound means compound formed by a combination of positive and negative ions. So it has the ability to lose its valence electron and becomes ion (cation) and F has the ability to gain one electron to become (anion), that's why $NaF$ is an ionic compound.

$$N{{a}^{+}}\to 1{{s}^{2}}2{{s}^{2}}2{{p}^{6}} \\\ {{F}^{-}}\to 1{{s}^{2}}2{{s}^{2}}2{{p}^{6}} \\\$$

Therefore, $NaF$contains $1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}$

Hence, the correct option is A. $NaF$

Additional Information: Sodium fluoride has bactericidal properties yet it is excessively harmful for use as an injury germ-free. Foundational fluoride use during pregnancy has not appeared to forestall tooth rot in youngsters Sodium fluoride is utilized as a bug spray. Utilized in the fluoridation of public water. The mono sodium salt of Sodium fluoride L-glutamic corrosive; utilized in treatment of encephalopathies related with liver maladies.

Note: A large group of Brønsted bases consists of the anions of weak acids. For example, ${{F}^{-}}$is the conjugate base or the weak acid,$HF$. In water, $NaF$ (s) will dissolve to produce $N{{a}^{+}}$ (aq), the conjugate base of a strong acid, which will not react with water.
