Question

Predict the products of the following reaction: NaI+CaCl2à Separate the products with a comma. Do not use subscripts. For example, if the products are NH3 and H2O the answer would be entered as: NH3, H2O

Answer 1

The products of the reaction between NaI and CaCl2, based on a double replacement reaction, are sodium chloride (NaCl) and calcium iodide (CaI2), both of which likely remain in solution as aqueous ions.

Step-by-step explanation:

To predict the products of the reaction between NaI and CaCl2, we use the principle of a double replacement reaction. This type of reaction typically involves two ionic compounds where the cations and anions exchange partners. Given the reactants, sodium iodide (NaI) and calcium chloride (CaCl2), we would expect the sodium (Na+) to pair with the chloride (Cl−), and the calcium (Ca2+) to pair with the iodide (I−).

The expected products of this reaction are therefore sodium chloride (NaCl) and calcium iodide (CaI2). However, since iodide ions (I−) and chloride ions (Cl−) are both common anions, they are likely to remain in solution as aqueous ions without forming a precipitate. The reaction would then be represented as:

NaI(aq) + CaCl2(aq) → NaCl(aq), CaI2(aq)
