Question

if the hydroxide ion concentration, (OH-) of a solution is 3.6 x 10^-3 , what is the ph of the solution ?

Answer 1

pOH=-log[OH-]

pH + pOH = 14

Answer 2

how do you use log on a cal ???

Answer 3

with mine you just press it after you've inputted the number, but some calculators are different

Answer 4

good stuff (Y)

Answer 11

sure

Answer 12

if the hydrogen ion concentration of a solution is 4.2 x 10 - 6 m , what the ph?

Answer 13

basically p(anything)=-log[anything]

so pH=-log[H+]

Answer 14

so log 4.2 ???

Answer 15

-log(4.2x10^-6)
