Question

Ca(oh)2 + naso4 = caso4 + na(oh)2 в ионном виде

Answer 1

Ca(OH)₂ + Na₂SO₄ = CaSO₄↓ + 2NaOH  - молекулярное

Са²⁺ + 2ОН⁻ + 2Na⁺ + SO₄²⁻ = CaSO₄↓ + 2Na⁺ + 2OH⁻ - полное ионное

Са²⁺ + SO₄²⁻ = CaSO₄↓ - сокращенное ионное

Answer 2

To write the balanced ionic equation for the reaction between Ca(OH)2 (calcium hydroxide) and Na2SO4 (sodium sulfate), first, let's start by identifying the ions present in the reactants and products:

Reactants: Ca(OH)2 dissociates into the following ions: Ca^2+ (calcium ion) + 2 OH^- (hydroxide ions)

Na2SO4 dissociates into the following ions: 2 Na^+ (sodium ions) + SO4^2- (sulfate ion)

Products: CaSO4 (calcium sulfate) dissociates into the following ions: Ca^2+ (calcium ion) + SO4^2- (sulfate ion)

NaOH (sodium hydroxide) dissociates into the following ions: Na^+ (sodium ion) + OH^- (hydroxide ion)

Now, let's write the balanced ionic equation by focusing on the ions that undergo a chemical change:

Ca^2+ (from Ca(OH)2) + SO4^2- (from Na2SO4) → CaSO4 (precipitate) 2 OH^- (from Ca(OH)2) + 2 Na^+ (from Na2SO4) → 2 NaOH (aq)

The balanced ionic equation for the reaction is:

Ca^2+ + SO4^2- + 2 OH^- + 2 Na^+ → CaSO4 (s) + 2 NaOH (aq)

Note: The "(s)" and "(aq)" notations indicate the states of matter. "(s)" denotes a solid precipitate, while "(aq)" denotes an aqueous (dissolved) substance.
