1. Only two substances are shown as dissociated in a total ionic equation: aqueous ionic compounds and aqueous strong acids. Write a balanced equation for the dissociation of each of the ionic compounds, including states of matter. 2. a) Write a balanced equation for the dissociation of each of the acids, as you did above for your ionic compounds, including states of matter. Assume they are strong acids (i.e. assume complete dissociation), disregarding the conductivity observations for now. b) Is it correct to assume complete dissociation for all acids? In other words, is it correct to assume that all acids are strong? Explain, citing observations made during the demo. c) Which acid is the “strongest”?___________________ d) Which acid is the “weakest”?____________________ 3. Should methanol be considered a hydroxide (ionic compound) or an alcohol (molecular compound), based on its observed conductivity? ______________________Why?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
