A Solution Is an Acid If Its PH Is Less $\left. \mathrm { H } ^ { + } \right]$

Multiple Choice

A solution is an acid if its pH is less than 7 and a base if its pH is greater than 7. The pH is defined by pH = -log10[H+],
where [H+] is the concentration of hydrogen ions in the solution. Use this information to answer the question
-A mixture has a pH of 7.6. Find the concentration of hydrogen ions [ $\left. \mathrm { H } ^ { + } \right]$ in the mixture. Is the mixture an acid or a base?

A) $10 ^ { 7.6 }$ , base
B) $10 ^ { - 7.6 }$ , base
C) $10 ^ { 7.6 }$ , acid
D) $10 ^ { - 7.6 }$ , acid
