Want this question answered?
The pH is the negative log of [H+].
pH is -log[H+] and can be found using pH meter.
10.56
by using buffers (if needed)
You usually calculate it with a pH stick. Good question!!.
This is the concentration of the ion H+.
Sodium chloride solution is neutral.
-log[H+] = pH therefore -log[0.001] = 3.00 The pH of a solution of 0.001 mol dm HC1? is 3.00
pH= -log = 1.59
This depends on what other acids or bases or buffering substances are in solution already, even if pH is neutral!
The molar concentration of the hydrogen ions
By using a universal pH indicator. If the pH indicator turns from red to blue, it will shows that it is a alkaline solution or a base, if the pH indicator turns from blue to red, it shows that it is an acidic solution. Hope its use full info for you>>>:)d
