10.1 Acids and Bases

10.1 Acids and Bases

  • In health, industry, and the environment acids and bases are important substances.
    • Lemons and grapefruits have acids that make them sour.
    • Lactic acid is produced when we exercise.
  • The production of yogurt and cottage cheese is affected by acid frombacteria.
  • Acidic water is electrolytes.
    • In water, hydrogen chlorides give hydrogen ion, H+, and chloride ion, Cl-.
  • A hydrogen ion and a negative ion can be produced by acids dissolving in water.
    • Hcl is an acid that is named hydrocyanic acid.
  • The hydrogen ion and the presence of acids can be produced by an acid dissolving in water.

  • Group 7A 17 can form more than two acids.
  • Antacids, drain openers, and oven cleaners are some of the household bases you may be familiar with.
  • It's completely in the water to give Na+) and OH-.
  • An Arrhenius base makes cations and OH- anions.
  • Give the name for H2CO3 if you identify it as an acid or a base.
  • There are conjugate acid-base pairs for Bronsted-Lowry acids.
  • The definition of acids and bases was expanded by J. N. Bronsted and T. M. Lowry in 1923.
  • H+ is donated by a substance called a bronsted-lowry acid.
  • A bronsted-lowry base can accept H+.
  • There is no free hydrogen ion in water.
  • A transfer of H+ from hydrogen chloride to water can be written as a hydrochloric acid solution.
    • Water is acting as a base by accepting an H+ in the reaction.
  • ammonia acts as a base when it reacts with water.
    • Water acts as an acid by donating H+ because the nitrogen atom of NH3 has a stronger attraction for H+ than oxygen.
  • Water acts as a Bronsted-Lowry base when HNO3 reacts with it.
  • Every acid-base reaction has two conjugate acid-base pairs because an H+ is transferred in both directions.
    • The conjugate base F- is formed when an acid loses one H+.
    • H3O+ is formed when the base H2O gains an H+.
  • The conjugate acid-base pairs can be identified using the relationship of loss and gain of one H+.
  • The loss and gain of one H+ is related to 2O/OH-.
  • Water can act as an acid when it donates H+ or as a base when it accepts H+.
    • The basic behavior of water depends on the other reactant.
    • Water donates H+ when it reacts with a stronger base and accepts H+ when it reacts with a stronger acid.
    • Bicarbonate is an amphoteric substance.
    • HCO3 acts as an acid and donates one H+ to give CO 2 3
  • The acid that loses H+ is identified.
    • H+ was donated to form the product.
    • The acid and the conjugate base are named after it.
  • The base is the reactant that gains H+.
  • NH3 is the base and NH4 is the conjugate acid.
