1. Consider this aqueous reaction. HNO3(aq)+Ba(OH)2(aq)⟶ What is the formula for the salt that forms? formula:
2.or the chemical reaction HClO4(aq)+NaOH(aq)⟶H2O(l)+NaClO4(aq) write the net ionic equation, including the phases. net ionic equation: Which ions are considered spectator ions for this reaction? Na+ ClO−4 OH− H+
1. Complete reaction is:
HNO3(aq) + Ba(OH)2 (aq)
Ba(NO3)2 (aq) + 2H2O (l)
So, Salt formed is : Ba(NO3)2 (aq)
2. Given molecular reaction:
HClO4(aq) + NaOH (aq)
H2O (l) + NaClO4 (aq)
Ionic reaction is :
H+ (aq) +ClO4-(aq) +
Na+(aq) + OH- (aq)
H2O (l) + ClO4-(aq) +
Na+(aq)
Spectator ions are ions which are same on either side of reaction.
So, Spectator ions are: Na+ and ClO4-
In net ionic reaction, ions which are same on either side of reaction are cancel out. SO, net ionic reaction is:
H+ (aq) + OH- (aq)
H2O (l)
