Question

What is the [H3O+] in Scientific Notation and the pH of ;
0.1 M
0.01 M
0.001 M
0.0007 M
0.0001 M
0.000001 M
0.0000003 M
0.0000001 M
0.0000000001 M
0.00000000002 M

Answer 1

Use: \(\sf pH=-log[H_3O^+]\)

Answer 2

Thank you I was a little lost. And this equation should help with notation and pH?

Answer 3

only for the pH.

there is no equation for scientific notation.

It's just a way to express the decimals in small numbers (or express really large numbers).

I'll show you two examples,

when you move the decimal point to the left 1000.0 = \(1.000*10^3\) you get a positive exponent.

when you move the decimal point to the left 0.0010 = \(0001.0*10^{-3}\) you get a negative exponent. You would really just write \(1.0*10^{-3}\)

Answer 4

i meant to the right on the second example, move the decimal point to the RIGHT

Answer 5

Oh ok. Thank you so much!

Answer 6

no problem!
