Consider the solubilities of a particular solute at two different temperatures.
Temperature (°C) Solubility (g/100 gH2O)
20.0 44.0
30.0 80.9
1. Suppose a saturated solution of this solute was made using 60.0 gH 2 O at 20.0°C. How much more solute can be added if the temperature is increased to 30.0°C?

We can still add 22.2 g of the solute

Explanation:

A saturated solution means that there is as much solute in the solution as its solubility allows.

First we calculate the mass of the solute present in a saturated solution with 60.0 g H₂O at 20.0°C:

The ratio of the solubilities at 20 °C and 30 °C is

This means that there can be 1.84 times more solute when the temperature is 30 °C.

So the mass of the solute that we can still add is:

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
