Web4 sep. 2024 · Ions can be grouped into two broad categories: cations and anions. Cations are ions that carry a net positive charge because the number of protons in the species is greater than the number of electrons. The formula for a cation is indicated by a superscript following the formula that indicates the number of the charge and a "+" sign. WebMolecules are the simplest unit of a covalent compound, and molecules can be represented in many different ways.

Typically the concentrations of H + in water in most solutions fall between a range of 1 M (pH=0) and 10-14 M (pH=14). Hence a range of 0 to 14 provides sensible (but not absolute) "bookends" for the scale. ctf pwn jmp rsp
