KI+H2SO4
Write the balanced net ionic equation.
If you had not changed screen names for your questions I would have caught it earlier. There is a system here. H2SO4 (a high boiling point acid) can be used to produce acids that have a smaller boiling point. Thus HI, HF, HCl, HBr, HNO3 etc can be prepared by heating a salt with H2SO4. You get answers a lot quicker if you keep the same screen name.
To write the balanced net ionic equation, we need to first write the balanced molecular equation and then break it down into ions to write the net ionic equation.
The molecular equation for the reaction between KI (potassium iodide) and H2SO4 (sulfuric acid) is:
2KI + H2SO4 -> K2SO4 + 2HI
Next, we need to break down the compounds into their respective ions to write the complete ionic equation:
2K+ + 2I- + 2H+ + SO4^2- -> 2K+ + SO4^2- + 2H+ + 2I-
Now, we can cancel out the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the reaction. In this case, the potassium ions (K+) and sulfate ions (SO4^2-) are spectator ions, so we can remove them:
2I- + 2H+ -> 2H+ + 2I-
Finally, we can simplify the equation to write the net ionic equation:
2I- + 2H+ -> 2I-
Therefore, the balanced net ionic equation for the reaction between KI and H2SO4 is 2I- + 2H+ -> 2I- .
