question 9 of 10\nwhich symbols below represent the ions found in a glass of water?\na. o₂ and h₂\nb. oh⁻ and h⁺\nc. co₂ and o₂\nd. nh₃⁻ and h⁺
Answer
Answer:
B. $OH^-$ and $H^+$
Explanation:
Step1: Recall water - ionization
Water undergoes self - ionization. $$H_2O\rightleftharpoons H^++OH^-$$
Step2: Analyze options
A. $O_2$ and $H_2$ are gases, not ions in water. C. $CO_2$ and $O_2$ are also gases, not ions in water. D. $NH_3^-$ is not a common ion in water, and the combination is incorrect. Water dissociates into $H^+$ and $OH^-$ ions, so B is correct.
