Solubility Curve
The salt with the highest solubility at 10 degrees C.
What is KI?
The covalent exception for conductivity
What are Acids?
The unit that is often used to express Molar Solubility
What is mol/L (M)
What is Ag+, Pb2+ or Cu+?
Technique used to filter out solids from liquids
What is using filter paper or decanting?
As temperature increases, solubility decreases for these particles.
What are gases?
Name a compound that is soluble in water and one that is insoluble in water.
What is NaCl and CH4?
A solution which has dissolved the maximum amount of substance
What is a saturated solution?
This solution produces the highest [OH-].
a. AgOH b. Sr(OH)2 c. Fe(OH)3 d. Mg(OH)2
What is c. Fe(OH)3 ?
The process/technique used to separate ions from a solution
What is selective precipitation?
The highest solubility gas at 50 degrees C.
What is HCl?
Covalent solutes that don't conduct electricity
What are non-electrolytes?
When the rate of dissolution equals the rate of crystallization in a solution
What is equilibrium in dissolving solutions?
Concentration of chloride ions if [CaCl2]=2.5M
What is 5.0M?
When sodium nitrate solution and potassium chloride solution are mixed, it creates a clear solution. What could you conclude with this?
What is no precipitation formed?
The temperature when KCl has a solubility of 44g/100g H2O.
What is 55 degrees C?
Solutions that contain non-electrolytes and solutions that contain electrolytes
What are molecular and ionic solutions?
The sign used in solubility equations when solutions are not highly soluble
What are double arrows?
The net ionic equation when calcium nitrate and potassium hydroxide are mixed.
What is Ca2+ + 2OH- -> Ca(OH)2?
When aqueous solutions of sodium chloride and silver nitrate are mixed, a precipitate forms. Adding an ammonia solution causes the solid to disappear, what is the precipitate formed?
What is AgCl? (Silver chloride)
The solubility in g/mL of KClO3 at 20 degrees C.
What is 0.1 g/mL?
They are structures held by electrostatic forces, causing them to form a repeated pattern where each ion attracts opposite charges
What are crystal lattices?
The process where salt dissolves faster than its ions can precipitate
What is the cause of movement towards dissolution?
Ag2SO4(s) -> 2 Ag+(aq) + SO42-(aq)
Initially, Ag2SO4(s) is in equilibrium with a saturated solution. Then at t1 more Ag2SO4(s) starts dissolving.
What is decreasing Ag+ or SO42- ion concentration?
Solution to separate hydroxide and sulphate.
What is Sr(NO3)2?
