4. pH Levels in Chemistry – The pH scale, which measures the acidity or basicity of a solution, is logarithmic. pH is defined as the negative logarithm of the hydrogen ion concentration in a solution. This means that each unit change in pH represents a tenfold change in hydrogen ion concentration.
The letters “pH” represent the French words “pouvoir hydrogene” which means “hydrogen power”. • The definition of pH is pH is equal to the negative log (logarithm) of the ____________ hydrogen ion concentration of a solution. • The logarithm of a number is the power to which 10 must be raised to equal that number.
Free printable worksheet on the power rule with answer key of logarithms includes model problems, practice problems, and challenge problems.
For each of the following solutions: Write a chemical equation, identify the limiting reactant (if there is one), and calculate the pH. We will calculate the pH of the solutions using the following 3 steps for each problem. Step 1: What is left in solution? Step 2: What are the equilibrium concentrations of the species in solution?
