Solubility Curves

Water chemical substance formula- H2O State at room temperature- Liquid Colour- Clear melt down point- 0oC Boiling point- 100oC Water- good solvent and a range of substances will throw out in it. What happens when a scratching lump dissolves in pissing? When the sugar dissolves -The moving piddle molecules crash into the sugar particles -The sugar particles then grass away from the crystal and into the water -The sugar and water particles then intermixture and diffuse evenly throughout.Copper sulphate- blue crystals, hydrated because they have water trap within them. When they are heated this water evaporates, the crystals become dehydrated and change state white. Equation for this Reaction. CuSo4 5H2O CuSo4 + 5H2O Solute- Solid which is dissolving Solvent- liquid in which the solute dissolves Solution- the solute and solvent miscellaneous together Sodium hydroxide- Soluble Copper Oxide- insoluble Calcium hydroxide- indissoluble Silver iodide- insoluble Aluminium nitrate- s olubleMost ionic substances will dissolve in water but covalent substances usually wont dissolve. Solubility of a solute = mass of a solid required to a saturate 100g of water at a particular temperature. Calculating Solubility 2g potassium chlorate dissolves in 20g water at 28oC what is its solubility? 2 x 100/20 = 10. 0g potassium chlorate/100g water 4g potassium sulphate dissloves in 30g water at 50oC what is its solubilty? 4 x 100/30 = 13. 33g potassium sulphate/100g water 0g sodium chloride dissolves in 75g water at 10oC what is its solubility? 30 x 100/75 = 40g sodium chloride/100g water Solubility Of Gases Carbon dioxide is the burn out which is dissolved in fizzy drinks to make the fizz. What happened when you placed sprite in a boiling tube and gave it a shake? The sprite fizzed up. What happened after you heated the sprite then gave it a shake again? If fizzed notwithstanding a little Carbon dioxide is more soluble in mothy liquid. The solubility of gases decreases as t he temperature increases.
