The solubility of co2 in water is 0.161 g/100 ml at 20oc and a partial pressure of co2 of 760 mmhg. what partial pressure of co2 is necessary in a soft drink canning process in order to allow the solubility of co2 to equal 0.886 g/100 ml?

The partial pressure of carbon dioxide having solubility 0.886g/100mL is 4182.4 mmHg

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

The equation given by Henry's law is:

      ......(1)

where,

= solubility of carbon dioxide in water = 0.161 g/100 mL

= Henry's constant = ?

= partial pressure of carbon dioxide = 760 mmHg

Putting values in equation 1, we get:

Now, calculating the pressure of carbon dioxide using equation 1, we get:

= solubility of carbon dioxide in water = 0.886 g/100 mL

= Henry's constant = 4720.5 g.mmHg/100 mL

= partial pressure of carbon dioxide = ?

Putting values in equation 1, we get:

Hence, the partial pressure of carbon dioxide having solubility 0.886g/100mL is 4182.4 mmHg

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
