What is the charge of a hydroxide ion (OH)?
A
0
B
−2
C
−1
D
+1
Verified step by step guidance1
Recall that a hydroxide ion (OH) consists of one oxygen atom and one hydrogen atom bonded together, carrying an overall charge.
Understand that oxygen typically has a charge of -2 in compounds, and hydrogen has a charge of +1 when bonded in ions like hydroxide.
Combine the charges of oxygen (-2) and hydrogen (+1) to find the net charge of the hydroxide ion.
Calculate the net charge by adding the charges: \(-2 + (+1) = -1\).
Conclude that the hydroxide ion carries a charge of \(-1\).
