Question | Answer |
colloids | size of solute- 1 to 1000, solute particles DO NOT settle, can be seperated with special equipment |
suspensions | size is greater than 1000 nm, particles settle WITH TIME, CAN be seperated by filtering |
solutions | size is .01- 1.0 nm, solute particles DO NOT settle, CAN NOT be seperated by filtering |
difference between solute and solvent | solute dissolves in solvent, while solvent is greatest component of solution |
factors that affect the rate of dissolving | stirring, temperature, surface area |
solubility of gases is affected by change of temp. by... | decreasing? |
pH levels- 1 to 6 | acid |
ph level 7 | neutral |
ph level 8 to 14 | bases |
Ex. 4- 6 on pH scale= | 100 times H+ ions |
NaCl -> Na + Nl | 1, dissasociation |
sugar | 4, nonelectrolyte |
2 H-lil2-0 <-> H-lil3-0 + OH | 2, equilibrium |
Na -> Na + E | 3, ionization |
NaNO3 solubility | steepest increase |
KNO3 solubility | medium increase |
NaCl solubility | no increase |
