 * Start of the
 * Copper (II) Nitrate :
 * a. Added water to Copper (II) Nitrate
 * Copper (II) Nitrate reacted with Sodium Hydroxide (NaOH)

- a bit warm || ||   ||
 * Heating Copper (II) Hydroxide

- color changes || ||   || Creates Copper (II) Oxide
 * Heating Copper (II) Hydroxide:

- color changed completely || ||   || - settled down || ||   ||
 * Copper (II) Oxide
 * Decant solution

- || ||   || - changes color to blue
