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
Methyl orange is frequently used as an indicator in acid titrations because it very clearly changes from red at a pH of 3.1 to orange at a pH of 4.4. Because the change in color takes place around the pH of most acids, methyl orange is commonly used for strong acid titrations and not for base titrations.Full Answer >
One of the main differences between acids and bases is that acids have a pH that is less than 7 and bases have a pH that is greater than 7. When dissolved in water, acids are substances that will cause the concentration of hydrogen ions (H+) to increase. Bases, when dissolved in water, will instead cause the number of hydroxide ions (OH-) to increase.Full Answer >
The pH of the mouth varies depending on the person. A healthy pH is above 7, and damage to teeth can occur if the pH is below 6.5.Full Answer >
The pH of a solution measures the amount of hydrogen ions that are in a solution. The term "pH" literally means "the power of hydrogen." The pH of a substance tells how acidic or basic a substance is.Full Answer >
