Answer:
Bronsted-Lowry acid and base
Explanation:
The definition of Bronsted-Lowry for a compound is in its ability to deal with any solvent, such as ammonia or sulfuric acid, through acids and bases in pairs, called conjugated acid-base.
A Bronsted-Lowry base is any species capable of <u>accepting a hydrogen proton</u>, which requires a pair of free electrons to form the bond with the H⁺ proton, whereas a Bronsted-Lowry acid is a species capable of <u>donating an H⁺</u>.
Thus, the conjugated base of a Bronsted-Lowry acid is the species formed after that acid donates a proton. The conjugated acid of a Bronsted-Lowry base is the species formed after that base accepts a proton.
The two species in an acid-base conjugate pair have the same molecular formula, except that the acid has an extra H⁺ compared to the conjugated base.

![{ \sf{XCO _{3} }}](https://tex.z-dn.net/?f=%7B%20%5Csf%7BXCO%20_%7B3%7D%20%7D%7D)
because X has only one positive charge.
7-
![{ \sf{increases}}](https://tex.z-dn.net/?f=%7B%20%5Csf%7Bincreases%7D%7D)
because there is increase in hydroxyl ions which decrease the acidity or hydrogen strength of hydrochloric acid.

![{ \sf{Ca(NO _{3} ) _{2} }}](https://tex.z-dn.net/?f=%7B%20%5Csf%7BCa%28NO%20_%7B3%7D%20%29%20_%7B2%7D%20%7D%7D)
Calcium has a valency of 2 and nitrate ion radicle has valency of 1
