4. Bleach products are sold as 5.25-7.5% hypochlorite concentration depending on whether they
are "regular" or "extra-strength"? How do your mass percentages compare to these values?
One of my valves falls into that range but the
other two fall a little short.
5. Bleach products slowly decompose over time eventually rendering them useless. What steps
can be taken to slow this (think back to the chapter on Kinetics) when storing your bleach
product?
The bleach products could be stored at a certain
temperature and kept away from the light. This
will help slow the decomposition.
6. As mentioned in the introduction, one type of bleach alternative uses hydrogen peroxide to
remove stains. The H₂O2 in the product can be titrated with the MnO4 under acidic conditions
by the reaction: 5 H₂O2(aq) + 2 MnO4 (aq) + 6 H* (aq)
5 02(g) + 2 Mn+2 (aq) + 8 H₂O(). If a
0.505g sample of a product containing H₂O₂ required 16.55mL of a 0.01158M MnO4 solution to
reach the end point, then what is the mass percent of hydrogen peroxide in this product
