The pH scale is a convenient way to represent the acidity or basicity of a solution. We can calculate the pH of a solution by taking the negative logarithm of the hydronium ion concentration, or pH = -log [H₃O⁺]. At 25°C, a solution with pH < 7 is acidic, a solution with pH > 7 is basic, and a solution with pH = 7 is neutral.Lesson 9 Acids and Bases Activity Acid: a group of chemical substances that have similar properties when dissolved in water.

Acids (pH < 7.0) react with bases (pH > 7.0) to produce a salt and water. When equal moles of an acid and a base are combined, the acid is neutralized by the base. The resulting mixture will have a more neutral pH.

An acid is a substance or compound that releases hydrogen ions (H +) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H + ), and chloride ions (Cl -) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding. In a weak acid, such as carbonic acid (H 2 CO 3 ...

A basic solution has a low H ^+ + concentration, less than that of pure water. To see …

This mechanism involves a buffer, a solution that resists dramatic changes in pH. Buffers do so by being composed of certain pairs of solutes: either a weak acid plus a salt derived from that weak acid, or a weak base plus a salt of that weak base. For example, a buffer can be composed of dissolved acetic acid (HC 2 H 3 O 2, a weak …The pH scale is a number scale that goes from 1-14. - The pH of a base ranges from 1-6. - The pH of an acid ranges from 8-14. - The pH of a solution that is neither an acid or base, or what we call ‘neutral’ (like water), is 7. The closer the pH number is to 7, the weaker the acid or base. Therefore, really strong acids will in the pH = 1-3 ...
