## Introductory Chemistry (5th Edition)

a. The concentration of $H_{3}O$+ is more than $10^{-7}$ hence the solution is acidic b. The concentration of $H_{3}O$+ is more than $10^{-7}$ hence the solution is acidic c. The concentration of OH- is more than $10^{-7}$ hence solution is basic. d. The concentration of $H_{3}O$+ is more than $10^{-7}$ hence the solution is acidic
