How are formulae used to write balanced chemical equations?
- OCR 21C All substances are described by their formulae, which are used to write balanced chemical equations. Writing the formula for an ionic compound requires knowledge of the charges on its ions. The formula of an ionic compound shows the relative numbers of the ions it contains. For example:
Which is the correct formula for the N a ion?
The N a ion has a +1 charge and the SO4 ion has a −2 charge. In order to give balance, we must have two Na ions to give an overall +2 with regards to Na: this, thus, neutralises the compound. Therefore, the formula is:
How do you write a formula for an ionic compound?
If you know the name of a binary ionic compound, you can write its chemical formula. Start by writing the metal ion with its charge, followed by the nonmetal ion with its charge. Because the overall compound must be electrically neutral, decide how many of each ion is needed in order for the positive and negative charges to cancel each other out.
How to write ionic charge based on name?
Write ionic charge based on the Roman Numeral in the name. For example, the Iron (II) ion would be Fe 2+. Polyatomic ions are made up of two or more elements (they will be non-metals).
