When water ionizes one of the hydrogen atomsabscondswith itself and leaves it's electron behind, giving usthehydroxide ion. The extra electron gives hydroxideanet charge of -1. The brackets indicate that this is anion,charge is denoted at top right.
Accordingly, what is the formula of hydroxide?
OH−
Also to know is, what is the charge for the hydroxide ion in NaOH?
The formula for hydroxide is OH-. Inthiscompound, oxygen bonds with hydrogen by sharingtwoelectrons. Hydroxide carries a negativechargebecause it has gained an electron.
10 electrons
