loss and fluid intake. For example‚ the loss of fluid through heavy sweating in hot weather reduces urine amounts. The minimum volume of urine needed to remove body wastes from an adult is about 500mL/day. The specific gravity of urine can be an indicator of disease or disruption in normal metabolism. As you recall from our earlier discussions‚ specific gravity measures the concentration of dissolved solids in a liquid without indicating what those solids are in the past‚ hydrometers were used to

(Absorbance on y-axis‚ concentration on the x-axis.) * Know how to use the data from a calibration curve to find (1) slope and (2) equation of the line. * How are absorbance and transmittance related? We discussed several equations: A = log (100/%T) A = (I0/IT) T = (IT/I0) x 100% A = 2 – log (%T) * What is Beer’s law and what does it describe? Rates

Housing starts lowest in months Housing starts are the number of new residential construction projects that are being done at a given time. When housing starts are particularly low it could mean bad news for the economy and also for both large and small businesses. If houses are not being built‚ people are not spending money on the initial construction. If there’s not construction‚ there are no jobs being

units of the pH scale and be able to distinguish between acid‚ base‚ and neutral compounds using the pH scale. Q8-1: What is something with a pH of 8? Q-8-2: A pH of 6 or lower results in what kind of compound? Concept 9: Understand Kw and its relationship to the ionization of water. Understand the relationship between [OH-] and the [H+] or [H3O+] in acidic and basic solutions. Q-9-1: Determine how many more times more basic the first pH is versus the second pH pH of 5 vs. pH of 3 Q-9-2:

This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order

stronger and acidic if the acid is stronger. If both are of equal strength‚ then the equivalence pH will be neutral. However‚ weak acids are not often titrated against weak bases because the colour change shown with the indicator is often quick‚ and therefore very difficult for the observer to see the change of colour. The point at which the indicator changes colour is called the end point. A suitable indicator should be chosen‚ preferably one that will experience a change in colour (an end point) close
