Which anion testing solution produced the fewest (< 3) precipitates? b) salts of these anions may be described as soluble with few exceptions. name the cations that are the exceptions to the rule for each anion identified in 3a

anions with least precipitates are anions of salt produce by a strong acid and strong base e.g KCL,Na2SO4,

Explanation: salts produce from strong acid such as HCL and a strong base such as KOH are extremely soluble and hence produce little or no precipitate when dissolved in water .meaning the salt are highly soluble , most group1 elements form salts that are highly soluble and hardly precipitates e.g Na(sodium) pottasium(K) ,lithium(Li)salts.they are called alkaline metals.

B) exception to the rules are hydrogen and Rubidium.hydrogen because it occurs basically as a gas and forms H^+ which tend to form a hydrogen bond while rubidium is a heavy metal forming insoluble salt

um i think it might be a car?
