Which option is true about the effect of polarity on solubility?
Alex777 [14]

Explanation:

It is known that like dissolves like. Therefore, polar solutes are soluble in polar solvents.

For example, salt is a polar compound and water is a polar solvent. Therefore, salt will dissolve in water.

On the other hand, oil is an inorganic solvent and hence, it is unable to dissolve any polar solute.

Therefore, we can conclude that following is true about the effect of polarity on solubility.

  • <em>Polar solutes dissolve better in water than in oil.</em>
  • <em>Polar solutes have the greatest solubility in polar solvents.</em>

What is the oxidation state of each element in k2cr2o7?
Stells [14]
To begin this, you'll first note down the valencies of atoms you're sure about.

K is always 1+
And O is always 2-, except for in peroxide where it is 1-.

So now you must remember that a compound is always neutral. Your net charge has to be 0.

K2Cr2O7.

K2 (1+ x 2) = 2+
Cr (2x) = 2x
O7 (2- ×7) = 14-

+2 +2x + (-14) = 0
•Simple algebra.
2x -12 = 0
2x = 12
x = +6.

Each Cr atom has an oxidation number of +6.
