Acids and bases

  1. 1. Acids• Most acids start with the element H, hydrogen – EX: HCl (hydrochloric acid), H2SO4 (sulfuric acid)• Any compound that increases the number of hydronium ions, (H+), when dissolved in water is an acid
  2. 2. • Has sour taste (think vinegar or lemons)• NEVER TASTE, SMELL OR TOUCH ACIDS• Corrosive – destroys body tissue, clothing and other materials• React with some metals to produce hydrogen gas• Conduct electricity• Most widely made acid H2SO4
  3. 3. • Common uses of acids • Make paper • Paint • Detergents • Fertilizer• HCl common uses • Separating metals • Swimming pools to stop algae
  4. 4. Bases• Most bases end with OH-, a hydroxide ion, when dissolved in water• Has bitter taste and slippery feel (think soap)• Corrosive properties• NEVER TASTE, SMELL OR TOUCH BASE• Conducts electric current
  5. 5. • Commons uses of bases – Make soap – Make paper – Oven cleaner – Drain cleaner – Household cleaners – Antacids (treat heartburn – rolaids or tums)
  6. 6. Strong -vs- Weak Acids• Strong acids will have additional Hydrogen (H+) molecules in the compound• All of the Hydrogen molecules break apart when dissolved in water• EX:H2SO4 (sulfuric acid) compared to HCl (hydrochloric acid)• Both are very strong acids but H 2SO4 would be the strongest of the two
  7. 7. Strong -vs- Weak base• Strong bases will have additional hydroxide (OH-), molecules in the compound• All of the molecules of a base break apart when dissolved in water and produce hydroxide ions• EX: NaOH (sodium hydroxide) compared to Mg(OH)2 (Magnesium hydroxide)
  8. 8. Salts• Large group of compounds with similar properties• When a reaction occurs between an acid and a base, they neutralize each other• When an acid neutralizes a base, salt and water are produced• Indicators are use to identify acids and bases
  9. 9. • pH scale is used to determine if an acid or base is strong or weak (compared to other acids and bases) REMEMBER ALL ACIDS AND BASES ARE DANGEROUS• 7 on the pH scale is neutral (H2O)• Bases have a pH greater than 7• Acids have a pH less than 7.
