Presentation transcript:

A student put 25.0 cm 3 of Na(OH) solution with an unknown concentration into a conical flask using a pipette. The sodium hydroxide reacted with exactly 20.0 cm 3 of 0.50 mol/dm 3 HCl added from a burette. What was the concentration of the sodium hydroxide? 1)Moles of HCl added 0.50 x (20.0/1000) =0.010 moles of HCl 2) Moles of Na(OH) moles 3) Concentration of Na(OH) 25 cm 3 = dm /0.025 = 0.40 moles/dm 3

Solubility curves L.O.:  Explain how solubility changes with temperature and pressure.  Predict what will happen when we cool a saturated solution.

What is there in our water? Water contains calcium and magnesium salts.

What type of compounds dissolved in water? Ionic compounds dissolved in water. What about gases?

Solubility: amount of solute in grams that can be dissolved in 100 grams of solvent.

The solubility of most solid solutes increases as the temperature rises

Saturated solution A solution in which no more solute will dissolve
