Question

Medal and fan
How would you calculate the pH given the molarity of NaOH, or technically OH-?

Answer 1

@Abhisar @JFraser @Somy

Answer 2

luckily there there is a worked example of your question in my book lol

Answer 3

second part

Answer 4

Errr, that's in mol though, not molarity with a capital M. There wouldn't be any way to determine the liters.

Answer 5

whats in mole?

Answer 6

the concentration.

Answer 7

its in moledm-3

Answer 8

its unit of concentration

Answer 9

Yess, I know. I need the molarity though, meaning m/L

Answer 10

mol/L*

Answer 11

dear lol Liter is dm3

Answer 12

molarity and concentration are same thing
unit is mole/dm3 or mole/L
exact same thing

Answer 13

Oh. I didn't know that.

Answer 14

i didn't know it too when i just joined OS but here ppl use liters a lot so i got to know it somehow xD

Answer 15

Okay, well I took the concentration, raised it -log^x (x being the number), then subtracted that number from 14. Wouldn't that be right?

Answer 16

yeah i guess this is how it's saying

Answer 17

in a quick way lol

Answer 18

Alrighty then.

Answer 19

is it clear? or should i post the part of where it kinda explains what you need to calculate it or so?

Answer 20

No I understand that formula, I've used it before, I just wasn't sure if I was able to use it for molarity.

Answer 21

cool then :D

Answer 22

Thank ya(:

Answer 23

no probs :D
