Titration is used to determine the concentration of an unknown substance via the molar relationship expressed through the chemical reaction equation. Using these relationships, the pH value can be determined by calculating the concentration of hydrogen ions (H+) and applying the pH equation. Commonly...

which increases the pH level of the solution towards 7, making it less acidic. However, the pH level of an acidic solution cannot become greater than 7, because the water you add to dilute it is not alkaline.

What percentage of the Ca2+remains unprecipitated? (Ksp = 9.1x10-6) I tried solving for [Ca2+] using Ksp and then divided moles of Ca2+ in the solution by # of original moles then multiplied by 100. Can't seem to get it though. Help would be much appreciated, thanks!
Percent error is the difference between an approximate or measured value and an exact or known value. Here is how to calculate percent error.
