Untitled Document 1 Docx Experiment 14 Acids Bases о Experiment 14: acids, bases, salts and buffers “acids and bases are phun!!!” introduction: an acid is a substance that yields h ions when dissolved in water. and a base is a substance that yields oh ions when dissolved in water. salt results when an acid reacts with a base in a neutralization reaction. 3. what happens when a strong acid or strong base is added to a buffer system? use chemical equations to support your answer. a. adding a strong acid or base to a buffer system does not change the ph of the solution drastically. adding a strong acid to the buffer causes the weak base to react with the h and form ha.

Accordingly, the reaction between an acid and base is described as follows: the salt of a weak acid is formed when a weak acid reacts with a base. the net ionic equation for the reaction is: ha. oh. →a(. ) h0o(1) (3) the salt of a weak base is formed when a weak base reacts with an acid. the net ionic equation is:. Experiment 14: acids, bases, salts and buffers “acids and bases are phun” summary: a buffer is a solution of a weak acid and its conjugate weak base. in the first part of the lab, we will identify the ph of different solutions by using the experimental and the calculations methods.

Monir 1 using the 2 nd sample of the buffer and adding 0.10 m naoh & b) adding strong acid and strong base to water: 1) place 25.0 ml of trap water to a 100 ml beaker, approximate the ph using the 3 5.5 ph paper, using the burrete, add 10 drops of 0.10 m naoh, measure the ph and record the volume added, keep adding 10 drops at a time recording the ph and total additive volume until the ph. A mixture of a weak acid and its conjugate base (or a mixture of a weak base and its conjugate acid) is called a buffer solution, or a buffer. buffer solutions resist a change in ph when small amounts of a strong acid or a strong base are added (figure 7.1.1).
