answer five and six.
Q5: Two solutions (CaBr2 and Li,CO3) are mixed together to give the following reaction. (1) is this a neutralization, or precipitation, or oxidation-reduction reaction? (2) balance the reaction; and (3) write a net ionic reaction equation. CaBT2 + Li2CO3 ? Caco, (s) + LiBT2 06: What is the balanced net ionic equation for the reaction between aqueous solutions of acetic acid and sodium hydroxide? CH,CO:H(aq) + OH'(aq) ? CH3(aq) + CO32-(aq) + H2(g) CH,CO,H(ag)+ 3NaOH(o)CCO,H (aq)+ 3Na (o)+ H,O CH,CO,H CH, (aq)+CO (g)+HO CH3CO:H(aq) + ??'(aq) CH3C02-(aq) + H2O CHyCO2H(aq) + 2 Na+(aq) + 20H'(aq)? CHC022-(aq) + 2Na.(aq) + H2O
Explanation / Answer
Ans 5
Neutralization reaction - when an acid reacts with a base and a salt formation takes place, the reaction is Neutralization reaction. In the given reaction no acid base reaction takes place.
Precipitation reaction - when a precipitate (solid) forms (insoluble in water) from two aqueous solutions, the reaction is Precipitation reaction.
Oxidation - reduction reaction - when an element oxidized or reduced in the reaction, the reaction is Oxidation - reduction reaction also called redox reaction. In the given reaction neither element reduced nor oxidized.
The given reaction is precipitation reaction.
Balanced equation
CaBr2(aq) + Li2CO3(aq) = CaCO3(s) + 2 LiBr(aq)
Molecular ionic equation
Ca2+(aq) + 2Br-(aq) + 2Li+(aq) + CO3 2-(aq) = CaCO3(s) + 2Li+(aq) + 2Br-(aq)
Net ionic equation
Ca2+(aq) + CO3 2-(aq) = CaCO3(s)
