The Feasibility of Sodium Bicarbonate as a Stain Remover for Grease Abucay‚ Larry Fernandez‚ Ivan Gonzalez‚ Angelo Macabuhay‚ Michaelangelo Manlangit‚ Luis Alfonso Morales‚ Don Niel LSGH 2013-2014 The Problem and Objective: Stain removers in the market today have multiple health hazards that could endanger our health. Dangerous chemicals can cause irritation‚ health problems‚ dangerous fumes and other complications. The group aims to find a new alternative material for the removal of

adding an additional absolute ethanol (2mls). The solution was refluxed for 40 minutes and was removed from the heating plate. Distilled water (30mls) was added to the solution. Sodium bicarbonate (60mls) was added dropwise until the pH was approximately 8. The pH was monitored using pH paper. Adding sodium bicarbonate caused a precipitate of benzocaine to form. The precipitate was filtered out of the solution using vacuum filtration. The precipitate was allowed to dry for recrystallization. The

Anhydrous sodium sulfate was added to the filtered organic solution to absorb excess water. Although water has a higher affinity towards sodium sulfate than cyclohexanol‚ excess anhydrous sodium sulfate may lead to the absorption of cyclohexane and thus loss of product. Anhydrous sodium sulfate absorbs water due to its polarity and therefore may also absorb cyclohexanol because of its polar O-H bond. If too much anhydrous sodium sulfate was added to the solution‚ part of the product would be absorbed

intestines. Common Name: Baking Soda Scientific Name: Sodium Bicarbonate Formula: NaHCO3 Fundamental particles: Baking Soda is comprised of one Sodium ion (Na+) and one Bicarbonate ion (HCO3-) Usage: Baking Soda has many uses; it can be used in cooking as well as cleaning‚ as an antacid and can also be used to fight odors. Properties: Baking Soda is odorless and can be used as an antacid because of the Bicarbonate ion. Common Name: Antacids Scientific Name:

a condition whereby the gastric acid returns in greater concentration after the drug effect has ceased. Moreover‚ this class of antacids is not suitable for all patients owing to its components. For example‚ the usually high concentration of sodium bicarbonate present in these chemical antacids may be inappropriate for patients afflicted with hypertension or kidney failure. Non Absorbable Antacids The non-absorbable antacids though less prone to cause a rebound effect‚ have their fair share

Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change‚ effervescence (bubbles)‚ when light or heat given off‚ and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning)‚ synthesis‚ decomposition‚ neutralization‚ single replacement and double replacement. A combustion reaction is a reaction with oxygen‚ and
