Web29 jan. 2024 · Spectator Ion Definition . Spectator ions may be either cations (positively-charged ions) or anions (negatively-charged ions). The ion is unchanged on both sides of a chemical equation and does not affect equilibrium. When writing a net ionic equation, spectator ions found in the original equation are ignored. WebFirst, do a flame test on all the chemicals. Depending on which elements are present will mean they turn different colours: sodium chloride, and sodium carbonate will give a yellow colour. potassium chloride, potassium iodide, potassium sulfate will give a lilac colour. Then test them by adding dilute nitric acid (then silver nitrate). fluttering heart memes
