Question

Write the total ionic and the balanced net ionic equation for the following reaction: H₃PO₄(aq) + Ca(OH)₂(aq) → Ca₃(PO₄)₂(aq) + H₂O(l)

a) H₃PO₄(aq) + 3Ca²⁺(aq) + 6OH⁻(aq) → 3Ca₃(PO₄)₂(aq) + 6H₂O(l)
b) 3H⁺(aq) + PO₄³⁻(aq) + 3Ca²⁺(aq) + 6OH⁻(aq) → 3Ca₃(PO₄)₂(aq) + 6H₂O(l)
c) H₃PO₄(aq) + Ca(OH)₂(aq) → Ca₃(PO₄)₂(aq) + 2H₂O(l)
d) H₃PO₄(aq) + 2Ca(OH)₂(aq) → Ca₃(PO₄)₂(aq) + 2H₂O(l)

Answer 1

The total ionic equation is H₃PO₄(aq) + 3Ca²⁺(aq) + 6OH⁻(aq) → 3Ca₃(PO₄)₂(aq) + 6H₂O(l). The balanced net ionic equation is 3H⁺(aq) + PO₄³⁻(aq) + 3Ca²⁺(aq) + 6OH⁻(aq) → 3Ca₃(PO₄)₂(aq) + 6H₂O(l).

Step-by-step explanation:

The total ionic equation for the given reaction is:

H₃PO₄(aq) + 3Ca²⁺(aq) + 6OH⁻(aq) → 3Ca₃(PO₄)₂(aq) + 6H₂O(l)

The balanced net ionic equation for the given reaction is:

3H⁺(aq) + PO₄³⁻(aq) + 3Ca²⁺(aq) + 6OH⁻(aq) → 3Ca₃(PO₄)₂(aq) + 6H₂O(l)
