Calcium nitrate, represented by the formula Ca(NO3)2, is a salt formed from calcium hydroxide (a strong base) and nitric acid (a strong acid). When Ca(NO3)2 is dissolved in water, it dissociates into calcium ions (Ca2+) and nitrate ions (NO3–).
Typically, salts that result from the reaction of a strong acid and a strong base are neutral in solution. In this case, because both the parent acid (nitric acid) and parent base (calcium hydroxide) are strong, the resulting solution of calcium nitrate will not exhibit significant acidic or basic properties.
Therefore, when Ca(NO3)2 is dissolved in water, it will result in a neutral solution. The pH of the solution will be close to 7, which is considered neutral. In conclusion, Ca(NO3)2 does not form an acidic or basic solution; instead, it creates a neutral one.
