Acid-Base Introduction

This was a short overview of the acid-base aspect of the topic. There are a few new things added to what we were expected to know from last year:
  1. How to calculate pH from the hydrogen (actually hydronium) ion concentration.
  2. How to calculate the hydronium ion concentration from the pH
  3. How to link pH, hydronium ion concentration and properties, such as rate of reaction
We also found out a couple of "lies" from last year:
  1. pH goes below zero and above 14
  2. hydrogen ions in solution are actually hydronium ions (H3O+)
  3. Salts are not always neutral - they may be acidic or alkaline (basic)
