This gave us aqueous solutions of both the organic and inorganic compounds. ... By adding 3M HCl to our solution, the hydrogen ions would protonate the nitrogen group of m-nitroaniline, forming a salt compound which would dissolve into the aqueous layer. ... This way, we would be two immiscible layers: an organic layer containing only naphthalene dissolved in ethyl acetate and an aqueous layer containing the m-nitroaniline salt, protons, and chloride ions dissolved in water. ... We first wanted to test if the the two compounds had any sulfate ions or chloride ions since all of the given poss...

In this process an aqueous solution is the combination of hydronium ions with hydroxide ions to form water. ... The pH of a substance is the negative logarithm of the concentration of hydrogen ions in a solution. This means that as the pH increases, the amount of hydrogen ions is decreasing and, therefore, the substance is less acidic. Since this is a logarithmic scale, each time the pH increases by one, it represents a ten-time decrease in the amount of hydrogen ions. ...

Acids are substances that reacts with water to produce hydronium ion, H3O+, and bases are substances that produces hydroxide ion, OH-, in water. ... As a result two opposing reactions simultaneously occur, one that removes ions and one that forms ions. ... As more H+ ions are created in the above equilibrium equation above, the system adjusts itself to create more H+ ions. As more H+ ions are created, more HA must be broken down into H+ and A- ions, leaving less and less HA. ... However, if a base such as sodium hydroxide is added to an aqueous solution of HA at equilibrium, the following neut...

As a result some of the precipitate returns back to separate Silver and Chloride ions. ... If we consider worst case scenario where the maximum amount of chloride ions dissolve and remain in the solution the following concept helps to calculate the solubility of the Chloride ions: For this reaction, each mole of AgCl that dissolves produces 1 mole of both Ag+  ions and Cl- ions. The solubility would then equal the concentration of either the Ag+ or Cl- ions. ... None the less if this photochemical decomposition happens in the presence of excess Silver ions in an aqueous solution the following...

The crystal lattice of metals consists of ions NOT atoms. ... The ions formed have full outer shells. ... Water molecules form hydrogen bonds with negative ions. ... Molten or aqueous form undergoes electrolysis, which involves conduction of electricity because of the movement of the ions. ... The sodium ion in the centre is being touched by 6 chloride ions. ...
