What is the neutral pH level?

• A. 0
• B. 7
• C. 14
• D. 5

Answer: (B)

pH describes how acidic or basic a solution is by looking at hydrogen ion concentration. A neutral solution has equal amounts of H+ and OH−, which places pH at 7 on the standard scale. The scale runs from 0 to 14: numbers below 7 are acidic (more H+), numbers above 7 are basic (more OH−). So 7 is the neutral point, while 0 is extremely acidic, 14 is highly basic, and 5 is acidic. At room temperature, [H+] and [OH−] are both 1×10^-7 M in a neutral solution, giving pH = 7.
