Calculate the HCl concentration in H2O from the conductivity

[QUOTE="chemisttree, post: 6319733, member: 63073"] How many digits to the right of the decimal does your pH meter display? If only one, then: pH 1.5 is 10[SUP]-1.5[/SUP] = 3.2 X 10[SUP]-2[/SUP] mol/L pH 1.6 is 10[SUP]-1.6[/SUP] = 2.5 X 10[SUP]-2[/SUP] mol/L pH 1.7 is 10[SUP]-1.7[/SUP] = 2.0 X 10[SUP]-2[/SUP] mol/L You need to monitor more closely than this? (~5-6 millimolar resolution or roughly +/- 3 mmol) An extra digit resolution on the pH meter gets you an order of magnitude more resolution on concentration. pH will determine concentration. To convert that to total #moles you will need to measure final volume. Evaporation effects may be something that affects final volume as well, so a final measurement of volume will solve for all unknowns. [/QUOTE]
