Calculate the concentration of oxalate ion (c2o42–) in a 0.175 m solution of oxalic acid (c2h2o4). [for oxalic acid, ka1 = 6.5 ×
Darina [25.2K]

C2H2O4 C2HO4- + H+

0.175 - x x x + y

C2HO4- c2o42– + H+

x - y y x + y

K2 = (y) (x +y) / (x-y)

As, y << x

So, K2 = (y) (x) / (x)

K2 = y =6.1 × 10^–5

Hence, concentration of (c2o42–) 6.1 × 10^–5 M

How does the vapor pressure of water at 10°C compared with its vapor pressure at 50°C ?​
Sliva [168]

Answer: The vapor pressure of water at 10°C will be less as compared with its vapor pressure at 50°C.

Explanation:

Vapor pressure of a liquid  is defined as the pressure exerted by the vapors  in equilibrium with the liquid/solution at a particular temperature.

As Kinetic energy is dependent on the absolute temperature of the gas.

K.E=\frac{3}{2}RT

where R = gas constant

T = temperature

On increase in temperature, the kinetic energy of the molecules increase and thus more liquid molecules can escape to form vapours and thus will exert more vapor pressure.

Thus the vapor pressure of water at 10°C will be less as compared with its vapor pressure at 50°C.
