  • All group I and Ammonium (NH4+) compounds are water soluble.
  • All Nitrates (NO3-) are water soluble.
  • All Carbonates are water insoluble except Gp-I and Ammonium compounds.
  • All Lead (Pb) compounds are water insoluble except Pb(NO3)2.
  • All "Halides" (Cl- , Br- , I-) are water soluble except Pb and Ag.
  • All Sulphates are water soluble except Pb and Gp-II (Ca to Ba) compounds. [ PbSO4, CaSO4, SrSO4, BaSO4 --> INSOLUBLE ]
  • All hydroxides (OH-) are water insoluble except Gp-I, NH4+, and Gp-II(Ca to Ba) compounds. [ Ca(OH)2 , Sr(OH)2 --> SOLUBLE ]
This is taken from Sir Rizwan Khan Yousufzai's Notes. I hope they help :)

well for ) level purposes its good to learn all but if you want to avoid over cramming then skip hydroxides and hydroxides

  • Cu=Pink
  • CuO=Black
  • CuCO3=Green

  • BLUE
  1. Cu(OH)2
  2. CuSO4
  3. Cu(NO3)2
  • Gp-I, II, III and Zn
  1. metals = shiny silvery white
  2. compounds = white
  • NO2 =Brown gas
  • Sulphur= yellow colour solidgr
  • Oxidising Agents
  1. KMnO4 -> purple to colourless
  2. K2Cr2O7 -> Orange to green
  • Reducing Agents
  1. SO2 -> no color change
  2. KI -> colorless to brown
  • Group VII
  1. F2=pale yellow
  2. Cl2=yellowish green
  3. Br2=red brown
  4. I2=dark brown
  5. At2=black
I might have missed out a lot of them, but i hope these few will help.. I couldnt find more :x
