Question

You will have an opportunity to examine certain precipitation reactions and test the solubility rules shown in the table below. Empirical Rules for the Solubilities of Common Ionic Compounds Soluble Compounds Exceptions None Sodium, potassium, and ammonium compounds Acetates and nitrates Chlorides Sulfates None Lead and silver chlorides are insoluble. Calcium, barium, and lead(II) sulfates are insoluble. Insoluble Compounds Exceptions Carbonates and phosphates Sodium, potassium, and ammonium compounds are soluble. Hydroxides Sodium, potassium, and calcium compounds are soluble. Sodium, potassium, calcium, and ammonium compounds are soluble. Sulfides You will also examine a reaction in which a gas is formed and some reactions of acids

Explanation / Answer

answer: a)NaNO3 sodium nitrate is soluble in water, according to given table nitrates are soluble

b)NH4Br ammonium bromide ammonium compounds are soluble in water according to table

c) (NH4)SO4 ammonium sulfate is soluble in water because ammonium compounds are soluble in water according to table

d) (NH4)2CO3 ammonium carbonate is soluble in water according to given table.

e) BaBr2 is soluble in water

f)BaSO4 barium sulfate is insoluble in water according to given table sulfate of barium is an exception in solubility

g) Ba(OH)2 generally barium hydroxide is soluble in water but in the given table of hydroxide exception barium is not written. so maybe according to given table it is insoluble in water

h) BaCO3 barium carbonate is insoluble in water

answer3: Ba(OH)2 barium hydroxide is a strong base and others acid base don't know what you have seen in experiment give experiment details
