Question

Cu(NO₃)₂ is a ________.

1) strong acid
2) weak acid
3) strong base
4) weak base
5) non electrolyte

Answer 1

Cu(NO3)2 is not an acid or a base; it is a salt and a strong electrolyte, formed by the reaction of a strong base (Cu(OH)2) and a strong acid (HNO3).

Step-by-step explanation:

Cu(NO3)2 (copper(II) nitrate) is not an acid or a base; rather, it is a salt. This compound is a result of the reaction between a strong base (Cu(OH)2) and a strong acid (HNO3). When dissolved in water, Cu(NO3)2 dissociates completely into copper (Cu2+) ions and nitrate (NO3-) ions, which makes it a strong electrolyte. This is due to the fact that both copper hydroxide and nitric acid are strong electrolytes, making their resulting salts also strong electrolytes. Therefore, among the given options, Cu(NO3)2 is best described as a strong electrolyte, which is not one of the choices listed.
