How to balance HCl + Sr(NO3)2?

This reaction between HCl + Sr(NO3)2 is not balanced as the number of molecules in the reactants and product are not equal.

 Sr(OH)2  + HCl → SrCl2 + HNO3

  • So, we have to balance the reaction subsequently.
  •  We should first assign coefficients to all molecules present in the reaction. We use P, Q, R, and S as we have five molecules. The reaction will look like this,
  • P Sr(NO3)2 + Q HCl →R SrCl2 + S HNO3
  •  The labeled coefficients can be used as alphabets for reactants and products.
  • Sr = P+ R, O=6P + 3S, H=Q+ S  N = 3P+S.
  • we can calculate the coefficient values using by Gaussian elimination method.
  • P=1, Q=2, R=1,S=2
  • So, the balanced equivalence of the reaction is,
  • Sr(NO3)2  + 2HCl → SrCl2 + 2 HNO3 .

HCl + Sr(NO3)2 titration?

HCl + Sr(NO3)2 net ionic equation?

HCl and Sr(NO3)2 reaction has the following Ionic equation,

Sr2+ + 2NO3 1- + 2H+ + 2Cl → Sr2+ + 2Cl + 2H+ + NO31-

  • Write the balanced chemical equation and represent the states (physical) of reactants and products.
  • Sr(NO3)2 (s)  + 2HCl (aq) → SrCl2 (s) + 2 HNO3 (aq)
  • Salts, acids and bases dissociate into ions, but pure substances and molecules fail to do so. The final equation after dissociation is
  • Sr2+ + 2NO3 1- + 2H+ + 2Cl → Sr2+ + 2Cl + 2H+ + NO31-
