Final answer:
Some salts can form neutral solutions, while others can produce acidic or basic solutions. 2SrBr2 and 4LiF are examples of salts that will produce basic solutions in water. The hydrolysis of these salts results in the formation of hydroxide ions (OH-) and increases the basicity of the solution.
Step-by-step explanation:
A salt can be classified as neutral, acidic, or basic based on the acid-base properties of its component ions. Salts derived from the reaction of a strong acid with a strong base, such as sodium chloride (NaCl), potassium nitrate (KNO3), and lithium bromide (LiBr), form neutral solutions with a pH of 7. The ions of these salts do not undergo hydrolysis and therefore do not contribute to the acidity or basicity of the solution.
However, other salts can produce solutions that are acidic or basic. For example, 2SrBr2 and 4LiF are salts that will produce basic solutions in water. The hydrolysis of the component ions in these salts results in the formation of hydroxide ions (OH-) and increases the basicity of the solution.
