Interpretation:
Moles of KClO3 can be dissolved in 100 gm of water at 60 °C has to be calculated from the graph.
Concept introduction:
Solubility: Solubility can be defined as maximum amount of solute that can dissolve in known amount of solvent at a given temperature and pressure. During solution formation, solute and solvent particles collide with each other, so that the solute gets dissolves in solvent. Solubility is affected by raising the temperature of the solvent because the kinetic energy of its particles is increased, resulting in more-frequent collisions and collisions with greater energy than those that occur at lower temperatures.
Answer to Problem 11STP
0.171 moles of KClO3 can be dissolved in 100 gm of water at 60 °C.
In the graph, starts at 60 °C, go straight up until you hit the line of KClO3. Then go across until hit the Y-axis. The mass it shows is 21 gm. So, at 60 °C the solubility of KClO3 is 21 gm. Therefore 21 gm of KClO3 can be dissolved in 100 gm water at 60 °C.
0.171 moles of KClO3 can be dissolved in 100 gm of water at 60 °C.
Explanation of Solution
In the graph, starts at 60 °C, go straight up until you hit the line of KClO3. Then go across until hit the Y-axis. The mass it shows is 21 gm. So, at 60 °C the solubility of KClO3 is 21 gm. Therefore 21 gm of KClO3 can be dissolved in 100 gm water at 60 °C.
0.171 moles of KClO3 can be dissolved in 100 gm of water at 60 °C.
