How is pH calculated? Explain the meaning of the calculation, giving some examples of pH numbers and what they mean. How much more acidic is a solution with a pH of 3 compared to a pH of 4How is pH calculated? Explain the meaning of the calculation, giving some examples of pH numbers and what they mean. How much more acidic is a solution with a pH of 3 compared to a pH of 4.
Homework Answers
The pH of any solution is measure of the concentration of hydronium ions(H3O+) present. The formula to calculate pH is -
pH = -log[H3O+]
given pH are 3 nad 4, now
3 = -log[H3O+] =[H3O+] = e-3 =4.98 * 10-2M
4 = -log[H3O+] =[H3O+] =e-4 =1.83 *10-2M
HERE SUBSTANCE WITH pH 3 HAS HIGHER CONCENTRATION OF HYDRONIUM IONS WHICH MAKES IT A STRONGER BASE.
NOTE THAT LOWER THE pH STRONGER THE ACID AND VICE VERSA.

1. Calculation: Using the Henderson-Hasselbalch equation, explain mathematically why a solution is at a pH below the pKa for an acid that more than 50% of the molecules have the proton on (not off). 2. Calculation: If you have a pH of 5.5 for a weak acid with a pKa of 4.76, then is there more A- or more HA in the solution? Explain why in words using your knowledge of positive or negative log numbers.

) The acidity or alkalinity of a solution is described using the pH scale. Basically, pH (which stands for "potential of hydrogen") is a measure of how many H+ ions there are in a solution. As we saw in the previous question, the more H*s there are in a solution, the more acidic it is. The formula for calculating pH is given below: In words, pH equals the negative log base ten of the hydrogen ion concentration. Solution X has...

Part 2. An acid is a compound that releases hydrogen ions (H+) when dissolved in water, creating an acidic solution. An alkaline or base is a compound that releases hydroxide ions (OF when dissolved in water, creating an alkaline or basic solution. Both hydrogen ions and hydroxide ions are present in water because water molecules dissociate and reform, and dissolved substances add or remove ions. pH is the measure of how much...
