What is the solubility of La(IO₃)₃ in a solution that contains 0.100 M IO₃⁻ ions? (Ksp of La(IO₃)₃ is 7.5 × 10⁻¹²)

<u>Solution and Explanation:</u>

[La3+] = 0.1 M

<u>At the equilibrium: </u>

La(IO3)3 <---->     La3+     +         3 IO3-  

                    0.1 +s             3s      

\mathrm{Ksp}=[\mathrm{La} 3+][\mathrm{IO} 3-]^{\wedge} 3

7.5 * 10^{\wedge}-12=(0.1+s) *(3 s)^{\wedge} 3

Since Ksp is small, s can be ignored as compared to the 0.1

The above shown expression thus becomes:

7.5 * 10 \wedge-12=(0.1) *(3 s) \wedge 3

7.5 * 10^{\wedge}-12=0.1 * 27(\mathrm{s})^{\wedge} 3

s=1.406 * 10^{\wedge}-4 \mathrm{M}

<u>Answer: 1.4*10^-4 M </u>

PolarNik [594]
(2) U-238 is the radioisotope used in dating geological formations. Uranium-238 has a half-life of 4.46 billion years, which makes it suitable to date such old formations.
The other options do not have such long durabilities and half-lives.

Reduction occurs at which electrode?
OLEGan [10]

Answer:

The electrode that removes ions from solution

Explanation:

Each electrochemical cell consists of an anode and a cathode. Oxidation occurs at the anode and reduction occurs at the cathode.

At the anode, ions move from the electrode into the solution while at the cathode ions move from the solution to the electrode.

At the cathode, metal ions accept electron(s) and become deposited on the electrode hence this electrode removes ions from solution. This is reduction.
