Answer to Question #139699 in General Chemistry for Alexter

Question

Strontium Bromate solution was added to with more solute but can no longer be dissolved.
It was found that its concentration is 50.6%. What is the temperature of the solution?

Answer 1

Convert ocncentration to g of solute per 100 g of water:

$\frac{s}{100+s}=0.506$

$s=102.4$ grams per 100 g of water

According to CRC Handbook of Chemistry and Physics, 87th Edition

(http://www2.chm.ulaval.ca/gecha/chm1903/6_solubilite_solides/solubility_vs_temperature.pdf) the highest value of solute (Sr(BrO3)2) which can be dissolved in 100 g of water at 100 $C^\circ$ is 41 grams.

This means that some initial data is incorrect, as the mass of solute (102.4) is much bigger that the mass of Sr(BrO3)2 which can be disoolved in 100 g of water at 100$C^\circ$
