Solution a Has a PH of 4 $\mathrm { pH } = - \log _ { 10 } \left[ \mathrm { H } ^ { + } \right]$

Multiple Choice

Solution A has a pH of 4.9 and solution B has a pH of 8.8. The acidity (pH) is a measure of the hydrogen ion concentration H + (measured in moles of hydrogen per liter) of solution. Acidity is modeled by $\mathrm { pH } = - \log _ { 10 } \left[ \mathrm { H } ^ { + } \right]$ . The hydrogen ion concentration of solution A is how many times the concentration of solution B.

A) The concentration of solution A is approximately 7,943 times the concentration of solution B.
B) The concentration of solution A is approximately 3.9 times the concentration of solution B.
C) The concentration of solution A is approximately 20 times the concentration of solution B.
D) The concentration of solution A is approximately 3.6 times the concentration of solution B.
E) The concentration of solution A is approximately 1.8 times the concentration of solution B.
