When an ionic compound dissolves in water, the cations and anions are separated. Ions in solution will result in that solution conducting electricity, an electrolyte. Some solutions are strong electrolytes while others are weak electrolytes. 1. What do you think is giving rise to electrical conductivity? ions in a crystal 2. This is a diagram showing ions in a crystal. Draw a diagram showing the particles in 1) strong electrolyte, and 2) weak electrolyte. Pay attention to how the water...

Describe the process that takes place between the participants in the neutralization reaction between the strong acid nitric acid, HNO3(aq), and the strong base potassium hydroxide, KOH(aq), forming water and potassium nitrate, KNO3(aq). Mention the nature of the particles in the solution before and after the reaction. (a) Because nitric acid is ---Select--- an acid a base a binary covalent compound a binary ionic compound an oxyacid , it reacts with water to form ---Select--- hydrogen atoms hydronium ions hydroxide ions protons...

When sodium acetate dissolves in water the resulting pH is above 7. This is because Sodium ion reacts with water to produce hydroxide ions. O Sodium ion is the cation of a strong base and acetate is the anion of a weak acid. Acetate ion reacts with hydroxide ions to produce excess protons. none of these answers Knowing the pH of a solution will allow one to know the pOH as well. O True...

MgCl2 is white as a solid and colorless if it dissolves in water. HCl is also colorless when it is dissolved in water If Mg is the limiting reagent, at the end of the reaction the solution will be completely transparent but there will be solid MgCl2 at the bottom of the flask. hydrogen gas will continue to bubble through the solution. Adding more HCl will make the reaction start again and produce more product. the solution will be completely...
