  1. Furthermore, is there an equation than can express the nth value of any prime number? For example, where n=1, F(n)=2 etc.
  2. It might be better to take a statistical approach from a real world study rather than starting with a hypothetical equation and trying to make the results fit. You'd need to assess an enormous number of people for your experiment (and the results) to be credible. There would also be the issue of "too many variables" and inquantifiable factors, such as medications, stress levels, demographics, recent exercise, hydration, blood-sugar concentration, illnesses, head trauma, childhood factors, discomfort, noise, body temperature, ambient temperature, gender, age, normal sleep patterns, work patterns, smells in room, blood pressure, bladder capacitance. Not that I'm trying to put you off. Go for it.
  3. Best all-round chemistry textbook in my opinion is Chemistry: An Integrated Approach by Housecroft & Constable (ISBN: 0-582-25342-X). Not at all pretentious and a very easy-to-follow text. Designed for first year undergraduates but I believe many non-undergraduates could understand it.
  4. What complicates this further is that sugar is not an ionic compound. Start by measuring relative solubilities of different salts and mixtures of salts in distilled water. Then see how the temperature of the solution affects the results. I would imagine you'd see a pattern form in your results. If anything interesting develops, post it on here.
  5. You can get pure sodium hydroxide if you shop around websites of cleaning companies. There's a cleaning company in Northern Ireland that delivers pure NaOH. You could always look on Ebay too, under the "Business, Office & Industrial" section.
