Net Ionic Equations! Please help me out!
i'm having a hard time with writing net inoic equations and here are some sample problems with the answers I came up with.
Please look over them and if somethings wrong, please correct the errors teach me how to fix it.
1. A strip of copper is immersed in dilute nitric acid
Cu + HNO3 -> Cu(NO3)2
2. Excess concentrated ammonia solution is added to a suspension of silver chloride.
Ag+ + OH- -> AgOH
3. Solution of tri-potassium phosphate and zinc nitrate are mixed
3Zn+ + (PO4)^-3 -> Zn3PO4
4. Concentrated hydrochloric acid is added to solid manganese (II) sulfide.
Mn^+2 + Cl2- -> MnCl2
and the rest of them below, I had no clue on how to even start
1. Potassium permanganate solution is added to an acidic solution of hydrogen peroxide
I got KMnO4 + H2O2 -> KMnO4 + H + O2^-2
but i hit the wall right here...
I'm guessing that the product is HMnO4 but I'm not confident at all.
2. Excess chlorine gas is passed over hot iron filings
Cl2 + Fe^2+ ? sorry..but i couldn't figure this one out either
3. Water is added to a sample of solid magnesium nitride
4. Excess sulfur dioxide gas is bubbled thru a dilute solution of potassium hydroxide
p.s. thank you so much for reading this. But if you have an extra time, would you give some tips on writing an ionic equations? or list some most common mistakes that students make when they first learn this?
