The pH scale is a convenient method for expressing the hydronium ion concentration of a solution. pH = log(1/[H+]) = -log [H+].
[H+] is the hydronium ion concentration in M (molarity), which is the number of moles of solute per liter of solution.

What is discrepancy between the calculated pH and the experimental pH of the buffer solution?
Air. Carbon dioxide from the atmosphere enters the aqueous solution and forms carbonic acid, which increases the concentration of hydronium, thus lowering the pH.
Can a pH of a water sample be calculated from a knowledge of its acidity?
Yes, the pH of water can be calculated from knowing its acidity. pH is defined as -log[H+]. This means that if one knows the concentration of hydrogen ion in solution, the pH is simply the negative logarithm (base 10) of that.
What is the pH of 3.210-9?
pH is defined as the negative log of the concentration of H+ ions in solution. If what you have given is said concentration, the pH can be calculated as follows: pH = -log (3.210E-9) = 8.49
What would be the pH of a neutral solution An acid solution A basic solution?
Neutral solution: pH =7Acidic solution: pH7.
How does a solution with a pH of 7 compare to a solution with a pH of 9?
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.

Neutral solution: pH =7Acidic solution: pH7.
How can the pH of a solution be calculated if the pOH is known?
We can subtract pOH from 14, using the formula pH + pOH = 14. This is only true at 14 degrees Celsius.
How does a solution with a pH of 7 compare to a solution with a pH of 9?
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.
What is the pH of 3.0 M KOH?
Molarity is the concentration of a solution, defined as moles per unit volume. Where, Molarity = moles / volume In this case the molarity of the HCl solution is 0.03 M The pH of this is calculated by the equation below pH = - log [H+] Where [H+] is the concentration of hydrogen ions/ protons present in the solution. As HCl only contains one hydrogen ion per molecule then the concentation of [H+] is 0.03 M Then the equation can be calculated (the minus sign is very important!) pH = - log 0.03 pH = 1.52 To summarise, Molarity of 0.03 M HCl solution is 0.03 M pH of 0.03 M HCl solution is 1.52
How does a solution with a pH of 2 compare to a solution with a pH of 7?
A pH 2 solution is 100,000 times more acidic than a pH 7 solution. pH 2 is acidic whereas pH 7 is neutral
What is the pH of resultant solution if solution with pH 3 and pH 8 are mixed?
The pH will be 7.that is, it is neutral
What is the pH of an aqueous solution if the concentration of H plus equals 0.00097?
pH s calculated as the negative log10 of the hydrogen ion concentration. So log10 of 0.000724 = -3.14 so pH= 3.14
The pH of ethanol?
the pH of ethanol can be calculated using its pKa value (pKa 15.9) and the Henderson-Hasselbalch equation. pH = pKa - log [AH/A] where [AH/A] the ratio of disassociated versus undisassociated species in solution.
PH of 4 than a solution with a pH of 5?
a pH of 4 is most acidic than a solution with a pH of 5. In general, the lower the pH, the more acidic the solution is.
