Answer to Question #139462 in General Chemistry for Elca Aplacador

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$C^\circ$
