solubility curves

Let us learn about solubility curves

a) Solubility curves give a general idea about the ability of a solute to dissolve in water, at different temperatures.

b) The solubility of the solute at any temperature, between the mentioned highest & lowest temperatures, can be more or less accurately read.

c) The mass of crystals deposited, when a saturated solution cooled from a higher to a lower temperature& can be calculated.

Best Example

As per the given graph, the solubility of potassium nitrate at 60oC= 110 g and at 50oC = 91 g.

Therefore, by cooling a saturated solution of potassium nitrate containing 100 g of water from 60oC to 50oC, 19 g of the solute (110 g - 91 g) is deposited in the form of crystals.

In our next blog we shall learn about cell potential I hope the above explanation was useful.Keep reading and leave your comments.

  1. It become an attractive part of a blog when author uses indirect speech while writing a blog. It shows your creative mind as well as make your written essay different from others. 学校专业选择
