Calculate the silver ion concentration in a saturated solution of silver(i)carbonate, ag2co3.
(ksp = 8.1

The silver ion concentration is 2.54 * 10^-4 M

Explanation:

Step 1: Data given

Ksp of Ag2CO3 = 8.1 * 10^-12

Step 2: The balanced equation

Ag2CO3 ⇌  2Ag+ + CO3^2-

Step 3: The initial concentration

Ag2CO3: X M

Ag+: 0M

CO3^2- : 0M

Step 4: The concentration at equilibrium

Ag2CO3: There will react X

Ag+: There will react 2X ⇒ we will have (2X) M

CO3^2-: there will react X ⇒ we will have X M

Step 5:

Ksp = 8.1 * 10^-12 = [Ag+]² * [CO3^2-]

Ksp = 8.1 * 10^-12 = (2x)² * X = 4X³

X = 1.27 * 10^-4

[Ag+] = 2X = 2 *1.27 * 10^-4 = 2.54 * 10^-4 M

The silver ion concentration is 2.54 * 10^-4 M

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
