Acid Base

• Acids

  • compounds that have sour taste
  • it produce protons or hydrogen ions in aqueous solution
• Bases ( Alkilis )

  • compound that has a bitter taste and slippery feel
  • produces hydroxide ions in aqueous solution
• Johannes Bronsted and Thomas Lowry

  • expanded the definition of acid and base
  • according to them, acids are proton donors and bases are proton acceptors
• Conjugate acid

  • formed when a proton is transferred to water
  • formed after a proton is lost
• water can act as a base and acid
• presence of hydrogen ion enables water to donate a proton, which makes water amphiprotic
• amphiprotic - can donate or accept proton
• Autoionization - refers to a substance ionizing itself
• the pH of a substance helps us understand how substances can be used and handled due to their corrosiveness
• Concentration - the amount of acid per liter of solution
• strength - the proton-donating ability of the acidic compound
• Acid Strength - gives the equilibrium position of its dissociation reaction in aqueous solution
• strong acid - completely dissociated in solution at equilibrium, such that equilibrium is shifted to the right, whether concentrated or diluted
• weak acid - partial dissociation, shifted to the left
• Oxaacids - acid compound wherein the replaceable hydrogen is always bonded to an oxygen atom
