To calculate pH from molarity, take the negative logarithm of the molarity of the aqueous solution similar to the following equation: pH = -log(molarity). pH is the measure of how acidic or basic a substance is, which refers to the concentration of hydrogen atoms that are present. Molarity is the concentration of a particular aqueous solution in moles, also known as Avogadro's number, per liter.Know More
An individual who already has the molarity of an aqueous solution can simply use a calculator with the molarity to determine what the pH of the solution. pH ranges from 0 to 14. A neutral pH, which is the pH of water, is 7.0 while a pH less than 7.0 is considered to be acidic. A pH above 7.0 is considered to be basic. Any solution that has a very acidic or basic pH is considered to be reactive, and will easily react with other molecules and elements found in various solution to produce different compounds.
The pH and pOH of an aqueous solution should equal to 14. This is to maintain the equilibrium of the ionization reactions that happen in the solution. In short, if the pH or the pOH of a solution is known, the other can be easily deduced through simple math.Learn more about Acids & Bases
The pH value for acetic acid depends on its molar concentration in an aqueous solution. Acetic acid with a molar concentration of 0.9 or approximately 1.0 M has a pH value of about 2.4, which is also the pH of vinegar that contains about 5 percent acetic acid. Acetic acid with a molar concentration of 0.1 M has a pH of 2.87, and 0.0001 M of acetic acid has a pH of 4.3.Full Answer >
Potential hydrogen, or pH, is the measure of the acidity or alkalinity of an aqueous solution. A solution is acidic if its pH is less than 7. If its pH is greater than 7, the solution is basic or alkaline.Full Answer >
Potassium nitrate or KNO3 is neither acidic nor basic; it is neutral and has a pH of 7. An aqueous solution of potassium nitrate contains ions of K+ and NO3-.Full Answer >
