Question

the oxides bao, cao, mgo and sro all produce alkaline solutions when added to water. which oxide produces the saturated solution with the highest ph?

Answer 1

CaO (calcium oxide) produces the saturated solution with the highest pH.

Step-by-step explanation:

The oxide that produces the saturated solution with the highest pH is CaO (calcium oxide).

When CaO is added to water, it undergoes a reaction to produce calcium hydroxide (Ca(OH)2), which is highly alkaline.

The hydroxide ions (OH-) released by Ca(OH)2 contribute to the high pH of the solution.
