4. Neutral water has a pH of 7. Each one-unit decrease i the pH means that the solution is 10 times more acidic. How much more acidic vinegar is than baking soda if vinegar has a ph of 3 and baking soda has a ph of 9? I think the answer is 10 to the 6th power but I don't know how to write out my work.

• Pre-Algebra -

vinegar - pH 3
baking soda - pH 9
9 - 3 = 6 units diff.
10 x 6 = 60x as acidic

10^6 = 1 million, so I can't see how that is right

10^1.77815 = 60
or, 6 x 10^1 = 60

is this a pre-algebra question or science?
