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. simplypawspetcareWebWhen we break this up into its ions, we get H2 (aq) + SO4 (2−) (aq) + 2 Na+ (aq) + 2 OH− (aq) → 2 Na+ = SO4 (2−) (aq) + 2 H2O (ℓ). So we can "cancel" the 2 Na+ (aq) and the SO4 (2−) (aq) on each side. Okay. Then the resulting reaction is H2 (aq) + 2 OH− (aq) → 2 H2O (ℓ). raytracing cyberpunk linux
