Explanation:
Hello, there are alot method to separate the impurities from water. One of those & best method for purification of water is Distillation.
During distillation the given apparatus are set as shown in figure. After arrangement we put the impure water in distillation flask & there are two mouth of flask one is attached to condenser & other is covered. There are two tubes in the middle of the condenser in which water comes in from one and water goes out from the other and this happens continuously. The condenser is used to convert the collected water vapours into liquid water so that it can be collected easily in recieving flask.

Answer:
You make aluminum phosphate which is an insoluble salt, so a precipitated is formed.
Explanation:
First reagent: Al(NO₃)₃
Second reagent: (NH₄)₃PO₄
This is the reaction:
Al(NO₃)₃ (aq) + (NH₄)₃PO₄ (aq) → AlPO₄ (s) ↓ + NH₄NO₃ (aq)
Al³⁺ (aq) + PO₄⁻³ (aq) ⇄ AlPO₄ (s) ↓ Kps
Salt from phosphate is formed.
Answer:
20.0
Explanation:
NaOH = (25.0) (0.100m) \ 0.125M = 20.0mL
A coordination number can be determined by the usage of an atom towards a molecule from seeing how many numbers of atoms would have to be combined together in an atom.
