How to wash your tiedye
Pre-fill your washing machine with hot water and 1/4 cup Synthrapol or Professional Textile Detergent. Rinse the tie-dyes thoroughly before putting in the machine. Leaving ties on, rinse under cold running water (faucet, hose or shower), to stop the dye reaction. Next rinse in warm water while you untie the folds, keep rinsing until water runs fairly clear. Throw in the machine as soon as it is rinsed, running it through a full cycle. Don't wash more than the equivalent of about 8 adult size t-shirts at a time or the water gets too muddy.
What this last sentence says is that it might be fun to get together with your friends to wash out the shirts, but don't do too many at a time, as it could get muddy.

Problem 44, pg 534, and the titration problem below:
PowerPoint for Fishy#1You have a large flask full of NaOH, which you’d like to use for titrant. You think it’s close to .1 M, but you’re not really sure. Fortunately, you have a small amount of pure benzoic acid, so you plan to do a titration. You weigh a small, precise amount of this monoprotic acid into a flask, and dissolve it in approximately 20 mL of distilled water.
Here’s what you need to know:
What is the molarity of NaOH? (precise)
- molar mass of benzoic acid: 122.12 g/mol
- mass of benzoic acid: 0.230 g
- mL of NaOH titrated: 18.55 mL

Henry's Law
Homework
Henry's law is one of the gas laws formulated by William Henry in 1803 and states: "At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid." An equivalent way of stating the law is that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid:
C=kPgas
where
- C is the solubility of a gas at a fixed temperature in a particular solvent (in units of M or mL gas/L)
- k is Henry's law constant (often in units of M/atm)
- Pgas is the partial pressure of the gas (often in units of atm)

Problems 50, 51, 59
Calculation of Freezing Point Depression
If the solution is treated as an ideal solution, the extent of freezing-point depression depends only on the solute concentration that can be estimated by a simple linear relationship with the cryoscopic constant ("Blagden's Law"):
- ΔTF = KF · b · i,
where:
- ΔTF, the freezing-point depression, is defined as TF (pure solvent) − TF (solution).
- KF, the cryoscopic constant, which is dependent on the properties of the solvent, not the solute. (Note: When conducting experiments, a higher KF value makes it easier to observe larger drops in the freezing point. For water, KF = 1.853 K·kg/mol.[7])
- b is the molality (moles solute per kilogram of solvent)
- i is the van 't Hoff factor (number of ion particles per individual molecule of solute, e.g. i = 2 for NaCl, 3 for BaCl2)
