solubility rules

• T or F

  ionic compounds are generally insoluble in water

  F - they are generally soluble in water
• what does knowledge of the solubility of ionic compounds help us determine?

  the most appropriate method for the preparation of salts
• are sodium, potassium and ammonium all soluble?

  yes they are all soluble
• T or F

  all nitrates are soluble


  T - none are insoluble
• are all chlorides soluble?

  • most are soluble
  • insoluble: silver + lead (II)
• T or F

  most sulfates are soluble

  T - barium, calcium + lead aren't
• T or F

  carbonates are mostly soluble


  F - most are insoluble, soluble: carbonates of sodium, potassium + ammonium
• are most hydroxides soluble?

  • no they are mostly insoluble
  • soluble: hydroxides of sodium + potassium + ammonium (calcium hydroxide is sparingly soluble)
