Let us discuss the product, type, and balancing of this reaction in this article.

 What is the product of HNO3 and Al(OH)3 ?

HNO3 and AgOH have the following products. Aluminum Nitrate (Al(NO3)3) and water (H2O).

Al(OH)3 + 3 HNO3 → Al(NO3)3 + 3 H2O

What type of reaction is HNO3 + Al(OH)3 ?

The reaction between HNO3 plus Al(OH)3 is a double displacement reaction.

How to balance HNO3 + Al(OH)3 ?

This reaction between HNO3 + Al(OH)3 is not balanced as the number of molecules in the reactants and product are unequal. 

Al(OH)3 + HNO3 → Al(NO3)3 + H2O

  • We should first give each molecule involved in the reaction a ratio. Because there are four molecules, we need P, Q, R, and S. The response will seem as follows:
  • P Al(OH)3 + Q HNO3 → R Al(NO3)3 + S H2O
  • You can use the labeled coefficients as reactant and product alphabets.
  • Al = P+ 3R, O=3P + 3Q + 9R + S, H=3P + Q + 2S, N = Q + 3R
  • The parameter values can be calculated using the Gaussian elimination method.
  • P=1, Q=3, R=2, S=3
  • So, the balanced equivalence of the reaction is,
  • Al(OH)3 + 3 HNO3 → Al(NO3)3 + 3 H2O

HNO3 + Al(OH)3 titration ?

 In the reaction between HNO3 and Al(OH)3, since HNO3 is a powerful acid and, therefore, cannot be utilized for titration, titration does not take place.

HNO3 + Al(OH)3 net ionic equation ?

HNO3 and Al(OH)3 have the following Ionic equation

Al(OH)3 + 3 HNO3 → Al(NO3)3 + 3 H2O

  • We should follow the steps to arrive at the net ionic equation.
  • Write the balanced chemical equation and represent the states (physical) of reactants and products.
  • Al(OH)3 (aq) + HNO3 (aq) → 2 Al(NO3)3 (aq) + H2O (aq)        
  • Salts, acids and bases dissociate into ions, but pure substances and molecules fail to do so. The final equation after dissociation is 
  • Al3+ + 3 OH1- + H+ + NO31- → Al3+ + 3 NO31- + 2 H+ + O2-

HNO3 + Al(OH)3 conjugate pairs ?
