|
ammonium bromide precipitates
|
|
|
potassium ammonium precipitates
|
|
|
no precipitate is formed
|
Detailed explanation-1: -On heating, ammonium bromide will decompose and escapes as gaseous ammonia and hydrogen bromide at high temperatures. As a result of this, the precipitate does not form. Thus, no precipitate is formed by the reaction of ammonium bromide and sodium chloride.
Detailed explanation-2: -Therefore, the chemical formula of potassium bromide is KBr. And we must use the state symbol aq to show that it is dissolved in an aqueous solution. According to the question, a pale-yellow precipitate is formed in the reaction.
Detailed explanation-3: -Yes, a precipitate is formed when these two are mixed. The empirical formula for that solid is NaBr(s) N a B r ( s ) and empirical formula of the given reactant are NH4Br(aq), NaOH(aq) N H 4 B r ( a q ), N a O H ( a q ) .
Detailed explanation-4: -Answer and Explanation: When aqueous solution of potassium hydroxide with ammonium nitrate leads to the formation of potassium nitrate aqueous solution and ammonia with water. We can see that no solid precipitate is formed in the product.
