Predict the chemical formulas of the compounds created by the following pair of ions: Ca2+ and also ClO3-.

Calcium chlorate is developed by the reactivity in between the ions Ca2+ and also ClO3-. The formula for calcium chloprice is Ca(ClO3)2.

The goal of this problem is to combine the 2 ions and develop a neutral compound. We desire this compound to have actually an all at once charge of zero, interpretation that the ionic charges need to balance each other out. This is bereason a molecule via no overall charge is more stable than a molecule via either positive or negative charge. The ions we are beginning through are unstable, and they will certainly be attracted to each other because of their oppowebsite charges. Note that a positively charged ion is dubbed a cation, and also an ion through negative charge is called an anion.

In this trouble, we are working through calcium as the cation and also chloprice as the anion. However before, the calcium ion has actually a charge of +2, which is twice as large as the chloprice ion’s charge of -1. (In chemistry, anytime you view an adverse authorize written by itself as a superscript on an ion, it means that the charge is -1.) Since of the distinction in magnitude of the charges, the calcium ion will certainly attract two chlorate ions (each via a -1 charge) to neutralize its charge of +2.

The overall equation would certainly look like this:

Ca2+ + ClO3- --> Ca(ClO3)2

To inspect your work, look at the charges in the last compound. The calcium brings a +2 charge to the compound, and each chloprice brings a -1 charge. 2 – 1 – 1 = 0, so the all at once molecule is neutral. You no much longer have to write out the ionic charges in the last compound.
