Question

Write a balanced net ionic equation for the principal reaction in solutions of each of the following salts. In each case, identify the Brønsted-Lowry acids and bases and the conjugate acid-base pairs.

1. Na_2CO_3
2. NH_4NO_3

Answer 1

the question is asking you to predict the reactions:

\(Na_2CO_3+H_2O\rightarrow \)

\(NH_4NO_3+H_2O\rightarrow \)

Answer 2

I get that half it is the other part besides the production of OH- that I don't have

Answer 3

\(Na_2CO_3+H_2O→ NaOH + NaHCO_3\)

Answer 4

for the net equation, remove the spectator ions

Answer 5

It says missing the charge and also elements being substituted for another

Answer 6

saying its incorrect

Answer 7

did you remove the spectator ions before inputting your answer?

Answer 8

No I guess I did not

Answer 9

wait are you mixing both of the reagents, or just mixing them in water?

Answer 10

water and its equilibrium problems. They are both separate problems sorry I didn't specify that

Answer 11

oh okay, so yeah, the net should look like: \(CO_3^{2-}+H_2O→OH^-+HCO_3^-\)

Answer 12

Okay and for the second one?

Answer 13

the second one is \(NH_4^+\) acting as an acid.

Answer 14

okay thanks a lot so it would be NH_4^+ + H_2O <=> OH^- + HNO_3^- ?

Answer 15

nope, \(NH_4^+\) is an acid, you'll make hydronium ions

Answer 16

okay I tried it and it was wrong, could you show me what it looks like as you did in the first one so I can better understand this one also?

Answer 17

thanks for spending the time to help

Answer 18

\(NH_4NO3+H_2O→H_3O^++NH_3+NO^-_3\)

you need to remove the spectator ions

Answer 19

no problem

Answer 20

NO_3 + H_2O<=>H_3O^+ + NH_3. I put this in an it says it is incorrect. Did I do something wrong?

Answer 21

\(NO_3^-\) is the spectator ion, \(NH_4^+\) is the acid.

Answer 22

Oh ya shoot that was a typo. I got it now. Thanks again

Answer 23

good stuff. no problem, work on identifying acids/bases
