Question

write the balanced net ionic equation for the following mixture: NaNO3 + KI

Answer 1

This is a double replacement reaction
So we can say that the balanced original equation is:
NaNO3 + KI ---> NaI + KNO3

Answer 2

Do you know your solubility rules to determine which product is solid?

Answer 3

no

Answer 4

We'll anything with NO3 or K is soluble. So we know that NaI is not soluble

Answer 5

Can you expand the equation using only ions?

Answer 6

im not sure

Answer 7

Okay so I'm gonna use parenthesis to show separate ions

(Na+) + (NO3-) + (K+) + (I-) ---> (K+) + (NO3-) + (KI)

Answer 8

Now cancel any ions that are on both sides of the arrow. Those are called spectator ions.
When you cancel we are left with....

(K+) + (I-) ----> (KI)

Answer 9

That's the net ionic equation
