I need to get a sample of seawater to a particular pH level by adding H2CO3 - presumably if I know the pH / molarity of the acid and the pH and volume of the seawater, it should be easy to calculate the volume of acid I need without messing around with trial and error - I'm sure I've done this before but I'm buggered if I can remember how its done - can anyone refresh my memory please?
when they discover mathematical dyslexia it'll be named after me so once again in english for the hard of thinking please Please Register or Log in to view the hidden image!
The concentration of Hydrogen Ions in a solution is equal to ten to the power of the negative pH number. In other words - for a solution with pH = 7, the concentration of Hydrogen Ions in that solution 1x10^-7 mol/l For a solution with pH = 1 the concentration of Hydrogen Ions is 0.1 mol/l. Another way of thinking about it is that pH = -log([H]) if that helps?
Ah! - you're using the ^ symbol as the "to the power of" symbol I was looking at it as the mathematical function "and" - makes sense now - cheers dude
