What is the oxidation state of each element in the compound Mg3Si2O5(OH)4 formed by replacing aluminum ions in kaolinite with magnesium ions?

Verified step by step guidance
1
Identify the oxidation state of oxygen (O) in compounds, which is typically -2.
Recognize that hydrogen (H) in hydroxide (OH) usually has an oxidation state of +1.
Assign the oxidation state of magnesium (Mg) as +2, which is common for alkaline earth metals.
Let the oxidation state of silicon (Si) be x. Set up the equation based on the compound's neutrality: 3(+2) + 2(x) + 5(-2) + 4(+1) = 0.
Solve the equation for x to find the oxidation state of silicon.
