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 in Acids & Bases
Hydriodic acid is an aqueous solution of hydrogen iodide whose chemical formula is HI. It is formed when hydrogen iodide (colorless gas with a sharp odor) is dissolved in water to form a pale yellow solution, which is strong and highly corrosive.Full Answer >
Acetone (C3H6O) has a pH of 7, which means that the substance, on its own, is neither an acid nor a base. This pH value, which is about the same as pure water, shows that acetone is relatively neutral. The organic compound is also known by the IUPAC name of propanone.Full Answer >
According to the University of California Santa Barbara, the pH of rubbing alcohol is about 5.5. This level can vary based on the dilution factor or the brand of the rubbing alcohol.Full Answer >
In chemistry, the main difference between pH and pKa is that pH tells the level of hydrogen ions in a certain medium while pKa value indicates the degree at which an acid dissociates or the side at which equilibrium is favored, according to Tutor Vista.Full Answer >
