Many acids and bases are colourless and can also form colourless products. What other observations can we make to determine whether or not a reaction is happening?
1) Explore acid and base solutions at the miscroscopic level using the two PhET simulations below.
2) Investigate the variables and write down any correlation between them. If you need a hint on which variables to investigate or how to write a hypothesis, you can expand the tabs below.
3) After you've written down all of your hypotheses, add one of them to the Padlet and extend or refine one of your peers' hypotheses.
strength of acid
strenght of base
pH
concentration of H3O+
concentration of OH-
concentration of HA
concentration of B
concentration of BH+
concentration of A-
concentration of MOH
concentration of M+
rate of dissociation
Water dissociates into the same moles of H3O+ and OH- ions.
Strong acids and strong bases completely dissociate into their ions whereas weak acids and weak bases do not.
4) Watch the video below for further explanation of the microscopic properties of acids and bases.
5) Find out if the substances in your research question are strong or weak acids/bases. Given an initial 1 mol of your acid/base, how many moles of dissociated ions do you expect at equilibrium?
