Question

CaCl2+KNO3розв'язати йонну реакцію

Answer 1

CaCl₂ + 2KNO₃ = Ca(NO₃)₂ + 2KCl

$Ca^{2+} +2Cl^{-} + 2K^{+} + 2NO_{3}^{-} = Ca^{2+} + 2NO_{3}^{-} + 2K^{+} + 2Cl^{-}$

т.к. в результате реакции получается раствор, содержащий ионы, на который диссоциируют соли, и нет ни осадка, ни воды, ни газа, считается, что реакция не идёт до конца

Answer 2

Ion Reaction of CaCl2 and KNO3

To determine the ion reaction of CaCl2 and KNO3, we need to first understand the chemical formulas of these compounds and then analyze their ionization in water.

CaCl2: - Calcium chloride (CaCl2) is a salt that consists of one calcium ion (Ca^2+) and two chloride ions (2Cl^-).

KNO3: - Potassium nitrate (KNO3) is composed of one potassium ion (K^+) and one nitrate ion (NO3^-).

When these compounds are dissolved in water, they dissociate into their respective ions:

CaCl2 dissociation: - CaCl2 → Ca^2+ + 2Cl^-

KNO3 dissociation: - KNO3 → K^+ + NO3^-

Now, let's consider the ion reaction when CaCl2 and KNO3 are mixed in an aqueous solution:

Ion Reaction: - Ca^2+ + 2Cl^- + 2K^+ + 2NO3^- → Ca^2+ + 2K^+ + 2Cl^- + 2NO3^-

In this reaction, the calcium ion (Ca^2+) and the potassium ion (K^+) exchange places, resulting in the formation of calcium nitrate (Ca(NO3)2) and potassium chloride (KCl).

This ion reaction demonstrates the exchange of ions between the two compounds, leading to the formation of new compounds in the solution.
