Final answer:
The acidic or basic nature of a salt depends on the acid-base properties of its cation and anion. KBrO2 is an acidic salt while LINO and NH4ClO are acidic salts.
Step-by-step explanation:
The acidic or basic nature of a salt can be determined by assessing the acid-base properties of its cation and anion. If the cation is a weak Lewis acid or the anion is the conjugate base of a weak acid, the solution will be acidic. If the cation is the conjugate acid of a weak base or the anion is the conjugate base of a strong acid, the solution will be basic. Neutral salts have cations derived from strong bases and anions derived from strong acids.
In the case of KBrO2, K+ is the cation and BrO2- is the anion. K+ comes from the strong base KOH, while BrO2- comes from the weak base HBrO2. Therefore, KBrO2 is an acidic salt. For LINO, Li+ comes from the weak base LiOH and NO3- comes from the strong acid HNO3, making LINO a basic salt.
For NH4ClO, NH4+ comes from the weak base NH3 and ClO- comes from the strong acid HClO, so NH4ClO is also an acidic salt.
