Which Bleach works better on tough stains?
Purpose
The purpose of this project is to determine which brand of bleach, Southern Home or Ultra Clorox works better on tough stains.
Our
hypothesis is that Clorox is going to work better than Southern Home because we
learned that when you buy an expensive brand you pay for what you get.
Introduction
Sunlight was the chief
bleaching agent up to the discovery of chlorine in 1774 by the Swedish chemist
K.W.Schecle and the director of its bleaching properties in 1785 by the
Frenchmen chemist Claude Berthollet. Bleaching
Powder, a solid combination of chemicals such as chlorine and slaked lime,
introduced in 1799 by the Scottish scientist and chemist Charles Tennant, was
thereafter produced in enormous quantity to bleach clothing and paper.
It had the
same effect as chlorine chemical and could be more easily handled and shipped,
but it was unstable and contained a large proportion of inert material. It
remained the standard bleaching agent until the 1920s, but then it was gradually
replaced by liquefied chlorine and solution of sodium hypochlorite.
Bleach is a
solid or liquid chemical used to whiten or remove the natural color of fibers,
yarns, paper, and textile finishing. The
bleaching process is used to produce white cloth, to prepare fabrics for other
finishes, or to remove coloration that has occurred in other processes.
Chlorine, sodium hypochlorite, calcium hypochlorite and hydrogen peroxide
are mainly used as bleaches. Bleach
is used for cleaning laundry that has a stain on it.
Bleach also disinfects around homes.
Bleach is one of the most fast-acting, most effective and economical
disinfectants world wide.
The two brands of bleach that were used in this experiment are Clorox and
Southern Home (a Foodmax brand product).
Clorox been making liquid bleach since it’s inception in Oakland,
California since May of 1913 sold at a $100.00 a piece.
It is estimated that 8 out of 10 homes us Clorox.
It is America’s leading brand of liquid bleach.
The bleach cycle:
1.
The bleach cycle starts with salt
water, which is broken down by electric current into sodium hydroxide, hydrogen,
and chlorine.
2.
The sodium hydroxide is mixed with
water. Next, chlorine is added to
form sodium hypochlrorite, the active ingredient in liquid bleach.
The bleach is bottle and shipped to retailers.
3.
Consumers use bleach in washing
machines or household surfaces. As
bleach reacts with stains and soils, it begins to break down. The cleaning process turns nearly all of the bleach back into
soft water.
4.
Any remaining bleach or in a septic
system through biodegradation. The
object of washing clothes is to remove soil, stains, bacteria and odors from the
fabrics. When bleach comes into
contact with large, chain-like soil molecules, it them down into smaller units.
These units have a harder time sticking to clothes.
Take
three 1000mL beakers and labeled them as followed:
In each of the three beakers add 400 mL of water. In the beaker labeled Clorox, add 100mL of Clorox liquid bleach. In the beaker labeled Southern Home, add 100mL of Southern Home liquid bleach. In the beaker labeled water, add an additional 100mL of water so that each beaker has been filled with 500mL of liquid.

Procedure
Take
three cotton socks of the same brand and style.
To each sock add 3mL of Juicy Juice grape juice.
Allow the juice to soak into the sock and dry.
After the socks have dried, place each sock in one of the labeled beakers
and allow them to soak for 5 minutes. Make
sure that each sock is allowed to sit for the same amount of time.
After 5 minutes, remove the socks from the beakers and lay them out to
dry. After they have dried inspect
the socks for remaining stains to see which brand of bleach removes stains the
best.
