WebJan 25, 2015 · This means that the concentration of the N a+ ions will be. 1.0 M ⋅ 2 moles Na+ 1 mole Na2SO4 = 2.0 M. Think of it like this: the volume of the solution remains constant, but the number of moles doubles; automatically, this implies that the concentration will be two times bigger for that respective ion. Here's how that would look … WebJul 4, 2024 · Omitting the water molecules bound to Cu 2+ for simplicity, we can write the equilibrium reactions as follows: The sum of the stepwise reactions is the overall equation for the formation of the complex ion: The hydrated Cu 2+ ion contains six H 2 O ligands, but the complex ion that is produced contains only four NH 3 ligands, not six.

WebIt all depends on whether the ionic crystal state (AgCl or NaNO3) is more thermodynamically favoured than the solvated ions (Ag+ and Cl- or Na+ and NO3-). By solvated, I mean that water molecules surround the ions and stabilise them so that they prefer to be in solution rather than sitting as a crystals at the bottom of the beaker. WebIons are identified by a superscript that shows the sign and size of the electric charge – for example Ca +2. There are two types of ions: cations and anions. A cation has a net positive electrical charge, which means it has more protons than electrons. An anion has a net negative electrical charge, which means it has more electrons than protons.
