solubility

Question 1

all are soluble

Answer 1

group 1 metal ions
eg. sodium (na+), potassium (k+)
ammonium (nh4+)
nitrate (no3-)

Question 2

all are soluble except
agcl, agbr, agi
pbcl2, pbbr2 and pbi2

Answer 2

chloride (cl-)
bromide (br-)
iodine (i-)

soluble ones are just +1 and -1 ions

Question 3

chloride
bromide
iodide
(group 17)
soluble or insoluble

Answer 3

all are soluble except
agcl, agbr, agi
pbcl2, pbbr2, pbi2

Question 4

sulfate (so42-)

Answer 4

all are soluble except
pbso4, baso4, caso4 and agso4
caso4 is sparingly soluble in water

Question 5

carbonate (co32-)

Answer 5

all are insoluble except group 1 carbonate and nh4+

Question 6

oxides (o2-)
hydroxides (oh-)

Answer 6

all are insoluble except group 1 metal oxide & hydroxide, ca(oh)2 and ba(oh)2
cao and ca(oh)2 are sparingly soluble to give aqueous calcium hydroxide, ca(oh)2 (aq) which is commonly known as limewater
