Volume
Dissolve a known amount of potassium permanganate in a known volume of demineralized water; calculate the concentration of manganese in the solution.
The percent concentration is 13,75 %.
Potassium Phisphate
Potassium iodide is neutral. So any solution of potassium iodide would have a pH of 7. One note: no substance has a particular pH as pH depends on both the acidity/basicity of a substance and how concentrated it is.
Of which concentration do you enquire?
The specified amounts of materials add to 814.78 grams total. Therefore, the percentage concentration by mass of potassium iodate is 100(3.05/814.78) or 0.374 percent, to the justified number of significant digits, and the percentage concentration by mass of potassium hydroxide is 100(6.23/814.78) or 0.765 percent, to the justified number of significant digits.
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
Lower concentration of solute is known as the hypotonic solution. The solution with a higher concentration of solute is the hypertonic solution. One with equal solute in solution and whatever its being compared with is known as the isotonic solution.
0,052 moles
Volume
The term to describe such a solution is CONCENTRATED.
Method: titration with a standardized solution of sodium (or potassium) hydroxide.
Method: titration with a standardized solution of sodium (or potassium) hydroxide.
The number of molecules in a given volume of solution depends on the concentration of the solute. Because the concentration is not provided, this question has too little information to answer.

The description of the concentration of a gradient shown in the transparency is a gradual change of solutes that are in a solution. This is a function of distance through the solution in biology.
