Free_Kalibri [48]

Based on their percent concentration, the 5% sugar solution contains more water.

<h3>What is the concertation of a solution?</h3>

The concentration of a solution is the amount of solute dissolved or present in a given volume of solution.

Concentration of solutions can be expressed as either:

  • molar concentration
  • mass concentration
  • percentage concentration

The concentration of the sugar solutions are given as percent concentration.

The 5% sugar solution contains 5% sugar and 95% water

A typical example of a specie that disproportionate is the copper I ion as shown below;

2Cu^+(aq) ------> Cu(s) + Cu^2+(aq)

The two oxidation states of copper formed in the disproportionation are Cu(0) and copper (II).
