The reactions of a diazonium salt are always done with a freshly prepared solution made in this way since the solutions do not keep. Nitrite ion is not stable water and accept a proton from a water molecule and form nitrous acid and hydroxyl ion. In this case, since all ions are in solution, and remain in solution after mixing, the net ionic equation will be the same as the ionic equation. The equation should include the states (g, l, aq, s). Nitrous acid decomposes very readily and is always made in situ. In NaNO2, An example where ionic equation would be different than the net ionic equation is the following. There are a total of 3 O atoms (H2O + CO2). Createyouraccount, {eq}\rm NaNO_{2}+HCl\rightarrow NaCl+HNO_{2}{/eq}. Once you know how many of each type of atom you have you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation.Important tips for balancing chemical equations:- Only change the numbers in front of compounds (the coefficients).- Never change the numbers after atoms (the subscripts).- The number of each atom on both sides of the equation must be the same for the equation to be balanced. If you want to know about the reactions of the diazonium ions formed, you will find a link at the bottom of the page.
