Could you use filtration on a solution?

Chemistry
1 answer:
Zinaida [17]3 years ago
4 0

Answer:

No.

Explanation:

This is because a solution is a mixture with two substances that have already dissolved in each other and so there is no residue left. Filtration works such that part of the mixture has smaller particles that can pass through the membrane of the filter paper while the bigger particles get stuck onto the paper as residue. A solution has a uniform size particle throughout and thus filtration does not work for purifying a solution.

An electrochemical cell has the following standard cell notation.
icang [17]

The cell notation is:

Mg(s)|Mg^{+2}(aq)||Ag^{+}(aq)|Ag(s)

here in cell notation the left side represent the anodic half cell where right side represents the cathodic half cell

in anodic half cell : oxidation takes place [loss of electrons]

in cathodic half cell: reduction takes place [gain of electrons]

1) this is a galvanic cell

2) the standard potential of cell will be obtained by subtracting the standard reduction potential of anode from cathode

E^{0}_{Mg}=-2.38V

E^{0}_{Ag}=+0.80V

Therefore

E^{0}_{cell}=0.80-(-2.38)=+3.18V

3) as the value of emf is positive the reaction will be spontaneous as the free energy change of reaction will be negative

ΔG^{0}=-nFE^{0}

As reaction is spontaneous and there will be conversion of chemical energy to electrical energy it is a galvanic cell.

Which statement best describes salts? Salts form from hydrogen ions and hydroxide ions in neutralization reactions. Most salts d
aliina [53]
<h2>Answer : Option D) Solutions of salt and water conduct electricity. </h2><h3>Explanation :</h3>

The best description of salt is that when they are dissolved in water they dissociate into ions and become electrolytic in nature. This is observed that these solutions of salt will conduct electricity. Dissociation of ions helps the solution to conduct electricity. Usually salts dissociate into respective cations and anions of the salt compound. Most of the salts can be obtained as a product from neutralization reactions.

Which of the following is NOT a way carbon dioxide returns to the atmosphere?
yawa3891 [41]

Answer:

emissions by factories is the answer

Explanation:

Factories produce air pollution which is polluted air, the other options

decay of organisms, photosynthesis (convert light energy into chemical energy - and returns CO2), and cellular respiration are all of the ways carbon dioxide returns to the atmosphere.

Hope this helped! Have a nice day, be safe and healthy :)
