Chem 111 Exp. 7 Part 2
Terms in this set (11)
Are compounds containing Na+, K+, and NH4+ soluble or insoluble?
Are compounds containing Cl-, Br-, I-, NO3-, and SO4 (2-) soluble or insoluble?
*There are some exceptions, but you don't need to know them for the quiz.
Are compounds containing OH-, PO4 (3-), and CO3 (2-) soluble or insoluble?
What are the three exceptions?
Na+, K+, and NH4+
a homogeneous mixture of two or more substances
What's a net ionic equation?
reaction equation without spectator ions
What's the difference between a polar and nonpolar molecule?
Polar has dipole moment, nonpolar does not
What's the chemical symbol for:
ammonia, carbonate ion, silver ion, bicarbonate ion?
What three interactions dominate the solubility of a solute in aqueous solution?
What's an "acidic" cation and a neutral cation
acidic cations react with water to produce H+, making an acidic solution (ie: Al 3+)
neutral cations don't react with water
What's the net ionic equation for the reaction of NaOH solution and HCl solution?
Na+ (aq) + OH- (aq) --> H20 (l)
What is "hydrogen bonding of water?"
Partial positive on hydrogen are attracted to partial negative on oxygen, which are fairly close together and form weak, hydrogen bonds.
These weak bonds are responsible for many of the interesting and unusual properties of water.
