Question 944226: The pH level of a type of vinegar is 2.9. What is the hydrogen-ion concentration [H+] for the vinegar? Use the formula pH= -logv10[H^+]
A.≈ 0.0013 M
B.≈ 0.0046 M
C.≈ 0.13 M
D.≈ 0.46 M Answer by josgarithmetic(39618) (Show Source):
You can put this solution on YOUR website! Better notation, pH=-log([H^+]), about the best to be done this way because the rendering will destroy part of it. A more convenient way to express this could be pH=-log(H), and we just need to know we are using base ten.
-log(H)=2.9
log(H)=-2.9
The meaning is,
Near 0.00126 M. You want to take this to two significant figures.
