Neutralization: Double displacement reaction → ions swap

Complete reaction: Sr(OH)2 (aq) + HNO3 (aq) → Sr(NO3)2 (aq) + H2O (l)

  •  Hydroxides (OH-) → insoluble except when with Group 1A ion and ammonium ion (NH4+) and Ca2+, Sr2+, Ba2+
  • Nitrates (NO3-) are soluble


To balance: add coefficient (if needed) so that the number of atoms for each element for both sides of the equation are equal.
