How to determine pH from key and molarity?
Most acids have a solution ph of less than 7, while bases have a solution pH greater than 7. To convert between these two so called “standard” solution pH values, use the following equation:
How to convert mass to molarity?
To convert grams of lactic acid to mass in moles, you first need to know how many grams of lactic acid are in one mole. We can determine this by dividing the molar mass of lactic acid (181.07 g/mol) by the amount of atoms in one mole of an atom: the number of atoms in a single proton is 1, so there are 6.02 × 1023 proton atoms in a mole of lactic acid. That gives us a
How to calculate pH from molarity and key?
To determine pH from just the molarity and key, you will need to know the number of moles of NaOH or HCl in a liter of solution (multiply the number by 0.1M to get number of grams of NaOH or HCl). This number can be found in the solution’s datasheet, or on the packaging.
How to calculate pH from key and molarity?
Commonly, pH is measured in water as a value of 7.0. In other words, a neutral solution has a pH of 7.0. A solution with a lower pH value is acidic, and a solution with a higher pH value is basic. The word acid refers to the H in the chemical symbol H2, while base refers to the OH in the chemical symbol H3O. Water is neither acidic nor basic.
How to convert molarity to pH?
The simplest way to convert molarity to pH is to use a pH calculator. Most calculators use the relationship: pH = - log [Molarity], where Molarity is the molarity of your solution. To determine the molarity to use with your calculator, you will need the concentration of your solution and the ideal pH for your solution. If you do not have a calculator, you can use a free online calculator.
