Factors of Solubility

Nature of solute and solvent, temperature, surface area, stirring, pressure

2
New cards

How many phases in a solution?

One

3
New cards

Properties of Solutions

homogenous mixture, dissolved particles will not settle out of solution, a single phase (aqueous), does not show the Tyndall effect

4
New cards

How do you make a supersaturated solution?

Heat the solution while adding solute and then cool to a lower temperature

5
New cards

Polyatomic ion with “universal solubility”

NO3/Nitrate

New cards

Properties of Acids

Sour taste, corrodes metal, high number of hydrogen ions, pH lower than 7, feels wet, turns litmus red

7
New cards

Properties of Bases

pH greater than 7, turns litmus blue, tastes bitter, high number of hydroxide ions, feels slippery
