Question

Write the net ionic equation, including the phases.2hno3(aq)+sr(oh)2(aq) ---> 2h2o(l)+srno32(aq)

Answer 1

Balanced chemical reaction: 
2HNO₃(aq) + Sr(OH)₂(aq) → 2H₂O(l) + Sr(NO₃)₂(aq).
Balanced ionic reaction:
2H⁺(aq) + 2NO₃⁻(aq) + Sr²⁺(aq) + 2OH⁻(aq) → 2H₂O(l) + Sr²⁺(aq) + 2NO₃⁻(aq).
Net ionic reaction:
2H⁺(aq) + 2OH⁻(aq) → 2H₂O(l).
(aq) means that substances are dissociated on cations and anions in water.
