Identify the conjuate acid and conjugate base. Calculate the pH of a 0.10 M NH 3 solution. M. Let's ignore y in the denominator. Compare this to the pH of 0.10 M NaOH, a strong base. You should be able to explain this using equations, words, and picture diagrams for weak bases vs. strong bases and weak acids vs. stong acids.
Pure water is neutral.
When you place NH 3 in water only a few OH- ions are produced, the solution is basic, but not as basic as the NaOH solution. We can show this using a picture diagram. When we make these comparisons we need to compare solutions that have the same initial concentrations. So far we have discussed obvious compounds that when palced in water will create and acidic or basic solution. Now we need to consider another class of compounds that are equally capable of created acidic or basic solutions when they are placed in water.
