Calculate the concentration of CO2 in water at 25 degrees Celsius when the pressure of CO2 over the solution is 4.5 atm. At 25 degrees Celsius, the Henry's law constant for CO2 in water is 3.1 * 10^-2 mol/L*atm.

? M

Answer : The concentration of is, 0.12 M

Explanation :

Using Henry's law :

where,

= concentration of = ?

= partial pressure of = 4.5 atm

= Henry's law constant  =

Now put all the given values in the above formula, we get:

Thus, the concentration of is, 0.12 M

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
