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 OH^1- + H⁺ + NO₃^1- → Al³⁺ + 3 NO₃^1- + 2 H⁺ + O^2-
