The deposition of XX and YY on ground surfaces is referred as wet and dry depositions, respectively. XX and YY are :

Options

  1. AX=CO2,Y=SO2X = {CO}_{2}, Y = {SO}_{2}
  2. B

    X=X = Ammonium salts

    Y=SO2Y = {SO}_{2}

  3. CX=X = Ammonium saltsY=CO2Y = {CO}_{2}
  4. DX=SO2Y=X = {SO}_{2}Y = Ammonium salts

Correct answer

B.

X=X = Ammonium salts

Y=SO2Y = {SO}_{2}

Step-by-step solution

Wet deposition is the acidic water received through rain, fog, snow, dew, mist, etc. Dry deposition is deposition of wind blown acidic gases and particles on the ground. Ammonium salt in rain drop result in wet deposition. Oxides of Nitrogen and sulphur settle down on ground as dry deposition.
