Answer:
All three statements are true
Explanation:
Solubility equilibrium of silver acetate:
- If pH is increased then concentration of
increases in solution resulting removal of
by forming
. Hence, according to Le-chatelier principle, equilibrium will shift towards right. So more
will dissolve
- If
is added then concentration of
increases in solution resulting shifting of equilibrium towards left in accordance with Le-chatelier principle. So less
- Insoluble precipitate of AgOH is formed by adding NaOH in solution resulting removal of
Hence all three statements are true
Answer:
Here's what I get.
Explanation:
At the end of the reaction you will have a solution of the alcohol in THF.
The microdistillation procedure will vary, depending on the specific apparatus you are using, but here is a typical procedure.
- Transfer the solution to a conical vial.
- Add a boiling stone.
- Attach a Hickman head (shown below) and condenser.
- Place the assembly in in the appropriate hole of an aluminium block on top of a hotplate stirrer.
- Begin stirring and heating at a low level so the THF (bp 63 °C) can distill slowly.
- Use a Pasteur pipet to withdraw the THF as needed.
- When all the THF has been removed, raise the temperature of the Al block and distill the alcohol (bp 143 °C).
