Detailed information about the chemical equation Cu + 2NaOH -> Cu(OH)2 + 2Na:
- Cu is the chemical symbol for copper, a soft metal with a reddish-pink color.
- NaOH is the chemical symbol for sodium hydroxide, a strong alkali.
- Cu(OH)2 is the chemical symbol for copper hydroxide, a blue solid substance.
- Na is the chemical symbol for sodium, a soft, light metal with a silver-white color.
-
Reaction conditions: The reaction conditions are all room temperature. However, this reaction is usually carried out in a strong alkali environment.
-
Reaction process: When copper reacts with sodium hydroxide, it creates copper hydroxide and sodium. This reaction is a substitution reaction, in which sodium replaces copper to form copper hydroxide and sodium.
-
Phenomenon occurrence: When the reaction occurs, you will see the copper metal gradually dissolve in the sodium hydroxide solution, creating a blue solid substance (copper hydroxide) and sodium.
