Identify the major ionic species present in an aqueous solution of C12H22O11 (sucrose).
Marina86 [1]
<h3><u>Answer;</u></h3>

No ions present

<h3><u>Explanation;</u></h3>
  • Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge.
  • Atoms that gain electrons and therefore have a net negative charge are known as anions. Conversely, atoms that lose electrons have a net positive charge are called cations.
  • C12H22O11 (sucrose) is not an ionic compound, and therefore does not have any ions. Sucrose is a molecular compound.

What are the four indications to recognize the chemical reaction?
Levart [38]
Five indicators of a chemical change are color change, temperature change, precipitate formation, gas bubble formation and smell or taste change. Since some chemical products are poisonous, detecting a chemical reaction via smell or taste change is not recommended.
