Question

help @surry99 ???

Answer 1

Precipitation reaction...
2Ag+ + CO3-- ----> Ag2C03

The reason it is called a ppt reaction is that the ions in solution (silver and carbonate) come out of solution by reacting and forming the ppt silver carbonate.

Answer 2

Notice how the moles of the elements are balanced as well as the total charge.
charge on the left is 0 (2-2) and the charge on the right is also 0

Answer 3

ppt reaction?

Answer 4

Also, this is Ag+ and Na2CO3...

Answer 5

yes...ppt is short for precipitation.

Answer 6

yes, the sodium ions are what we call spectators...they remain as ions in the solution but do not react...

Answer 7

Oh, I see.

Answer 8

When you mix the solutions together you get the silver ions combining with the carbonate to form the ppt silver carbonate and the sodium ions remain in the solution as spectators.

Answer 9

How come you have 2Ag+ ?

Answer 10

Charge must be balanced as well as mass in all reactions.

Answer 11

silver ion is +1 charge
carbonate ion is -2 charge
silver carbonate is zero charge
sodium ion is =1 charge

Answer 12

make sense?

Answer 13

This is so confusing...
Wouldn't it be...
Ag+ = 1 postiive charge
NaCO3 = CO3^(2-) = 3 ions with -2 charge
so... 1 + 3(-2) = 1 - 6 = -5 charge?

Answer 14

Look carefully at the formula for sodium carbonate...Na2C03
There are 2 sodium ions and 1 carbonate ion. Now the whole solid has no charge so the sum of the charges from the sodium and carbonate must add to zero.
Now if you know the charge on either one , then you can determine the charge on the other.
Do you know that the sodium ion is +1?

Answer 15

How do you know that the sodium ion is +1?
And if the sodium ion is +1, then the carbonate ion is -1?

Answer 16

hang on and I will send you a detailed solution in about 1 hour

Answer 17

Ok

Answer 18

@surry99 u there?

Answer 19

yes, I will be sending solution shortly.

Answer 20

ok

Answer 21

Give me 15 minutes to write it out

Answer 22

ok

Answer 23

just scanning to send it

Answer 24

kay

Answer 25

have a look and we can discuss

Answer 26

What's the aq in parenthesis mean?

Answer 27

Aqueous...it means dissolved in water

Answer 28

Oh, I see. And the (s) means solid. Thank you so much! I understand 100%. I'm sorry I had you do all this work....

Answer 29

no problem...any time!

Answer 30

Thanks again, and have a good night (or whatever, based on where you are). \(\Huge\color{#FFCC11}{\ddot\smile}\)

Answer 31

you are welcome!

Answer 32

I have a quick question. Is it possible for the two to combine if there isn't water present? Because the formula does not include H2O

Answer 33

The water is implied because the silver ion can only be stable in water.

Answer 34

Ah, I see. Thanks again. Bye!

Answer 35

Goodnight
