At room temperature, the solubility of which solute in water would be most affected by a change in pressure?

Carbon dioxide

Explanation:

Carbon dioxide is a product derived from the reaction of different processes, such as: the combustion of coal and hydrocarbons, the fermentation of liquids and the breathing of humans and animals. It is also in low concentration in the Earth's atmosphere.

The carbon dioxide structure is made up of molecules of linear geometry and non-polar character. In addition, at room temperature, the carbon dioxide solubility would be affected if a pressure change occurred.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
