Reactions in Aqueous Solutions Electrolytes 1- By using the table of solubilities of ionic compounds in water, predict which compound(s) in each of the following groups is (are) expected to be soluble in water? If a compound is soluble, write the equation for its dissolution in water. a) AgCI, Ag,PO AgNO, b) KCI, K CO,, KMno 2- Water is an extremely weak electrolyte, i.e., a very poor conductor of electricity. Yet we are often cautioned not to operate electrical appliances when our hands are wet. Why? 3- Explain the difference in the chemical meaning of the symbols: andExplanation / Answer
Solubility rules:
- Most alkali metal (group I metals) are always soluble
- Cations/Anions such as NH4+, HCO3-; ClO3-, NO3- are always soluble
- Most halides are soluble, F-,Cl-,Br-,I-, exceptions = Ag+, Hg2+2, Pb+2 compounds
- Most sulfates are soluble (SO4-2); exceptions = Ag+, Ca+2, Sr+2, Ba+2, Hg2+2, Pb+2 compounds
- In general (except all alkali metals) these ions will NOT be soluble: PO4-3, CrO4-2, S-2, CO3-2
Q1
a)
only AgNO3 will be soluble
b)
all are soluble, since K+ is alkali metal
c)
Only NO3- since all ntirates are soluble
d)
all are soluble, since Na+ is alkali metal
Q2
because we use Tap water, which contains ions in solution such as Na+, K+, Cl- etc..
these DO conduct electricity
Q3
--> means forward reaciton is favoured, i.e. production
<--- and --> implies equilibirum between products and reactants
