The following questions were asked by visitors named ChemHurts.

If 535 Ml of gaseous HCL, at 26.5 degrees Celsius and 747mm Hg, is dissolved in enough water to prepare 625 ml of solution, what is the PH of the solution?

The PH of an aqueous solution of NaCN is 10.38. What is [CN-] in this solution?

For the titration of 25.00 mL of 0.150 M HCl with 0.250 M NaoH, calculate (a) the initial pH; (b) the pH when neutralization is 50% complete; (c) the pH when neutralization is 100% complete; and (d) the pH when 1.00 mL of NaOH is added beyond the equivale...

Sorry for double posting but I got a solution of [CN-] = 0.0036 M. Can someone verify if that is right.

I determined the number of millimoles of HCl initially to be 3.75. How do I determine how much moles of NaOH are added at 50% completion for example because the volume isn't given.

Ok Thanks a lot guys.
