Answer:
Y(OH)₃
Explanation:
Given ions:
Y³⁺ OH⁻
To find a neutral compound that conforms with the formation of the given ions;
We us the exchange of valency approach to solve this problem. The valency will form the combining power of the ions for the combination.
Y³⁺ OH⁻
Combining power 3 1
Exchange of valency 1 3
Now the compound is Y(OH)₃
