An atom or a molecule can lose or gain electron(s) to form an ion. The formation of a precipitate can be used to identify the presence of a particular ion. of moles of the second product P2, $M_{R_{1}}$ = No. Lithium, sodium, potassium, calcium and copper compounds produce distinctive colours in flame tests: Sodium hydroxide solution can be used to identify some metal ions (cations). When an atom/molecule gains negatively charged electron(s), a negative ion is formed. Ions are atoms or molecules that carry a net electrical charge. The names of all the substances are present in the word equation. Particles can be atoms, molecules or ions. a. When two ionic compounds are dissolved into an aqueous state, or both are dissolved into the same solvent, their ions separate, so any ions that made up the first compound can interact with any ions from the second compound. After submitting the input equation, the output window opens which firstly shows the input interpretation. Just as there can be multiple atoms that make up a spectator ion, there can be multiple types of spectator ions in a particular reaction. Therefore, no precipitation reaction occurs. If you want, you can balance the equation for mass and charge first (at Step 1). The spectator ions are the ions that do not take part in the chemical reaction. Consider a precipitation reaction between two compounds KOH and HNO3 as represented below: KOH(aq) + HNO3 KNO3(aq) + H2O(l)K+(aq) + OH(aq) + H+(aq) + NO3(aq) K+(aq) + NO3(aq) + H2O(l).
