The Foods to Avoid that Causes Acid Reflux Problems in the digestive system should not be neglected. There are different possible digestive system disorders or diseases that are most often neglected by many people. The most common digestive problem is the acid reflux or gastro-esophageal reflux disease‚ mostly known as heartburn. Acid reflux affects different ages from infants to young children and adults as well. This disorder should be given special attention because it can lead to a more serious

What are trans fatty acids‚ and where do they come from? We’re used to hearing about saturated and unsaturated fatty acids. Saturated fatty acids - which come from animal fats (meat‚ lard‚ dairy products) as well as tropical oils such as coconut and palm oils - raise the levels of LDL cholesterol. Unsaturated fats - which come from vegetable oils - in general‚ do not increase cholesterol levels‚ and may reduce them. Because saturated fatty acids were found to be bad for you a couple decades ago

The Effects of Acid Rain on Plant Growth PURPOSE The purpose of this experiment was to determine to what degree acid rain affects the growth of certain plants. I became interested in this idea because I’m worried about our environmental conditions and it sounded very interesting to me. The information gained from this experiment may be used to as a warning to stop air pollution. HYPOTHESIS My hypothesis is that the plant watered with the acid solution will grow more slowly than plant’s

BUFFERS By: Luis P. Bazan‚ RPh.‚ Ph.D. A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the following

Crystallization of Benzoic Acid Purpose: The purpose of this experiment is to purify benzoic acid by crystallization. Procedure: 1. 0.5g impure benzoic acid was placed in a 50mL Erlenmeyer flask. 15mL of water was added and the mixture was heated to a boil on a hot plate. 0.5mL of water was added to the flask‚ while swirling the flask. The mixture was boiled until the benzoic acid completely dissolved. The total volume of water used was recorded. The black solid that remain in the dissolved

Name: Citric acid Chemical Name: 2-hydroxypropane-1‚2‚3-tricarboxylic acid Chemical Formula: C6H8O7 Chemical Structure: pH: 4.18‚ 3.90‚ 3.57 Classification: Weak acid Uses: It is a natural preservative/conservative and is also used to add an acidic or sour taste to foods and drinks. It is also used mainly as an acidifier‚ as a flavoring‚ and as a chelating agent. Name: Vinegar acid Chemical Name: Acetic acid or ethanoic acid Chemical Formula: C2H4O2 Chemical Structure:

of an object is determined using a process called titration. According to Petrucci et al.‚ titration is a reaction carried out by the carefully controlled addition of one solution to another. It has several types like acid-base titrations and redox titrations. This experiment focuses on the latter type‚ the redox titration. A redox titration is based on an oxidation-reduction reaction between analyte and titrant (Harris‚2009). It involves the transfer of electrons between the two solutions. This

Running head: ACID RAIN AND ITS EFFECTS Acid Rain: The Killer Rain Twanda Banks Grantham University April 5‚ 2011 Abstract Every time you turn on the television or take a ride in a car‚ you could be contributing to a problem called acid rain. Acid Rain is a serious problem with devastating effects. Every day this problem increases. Many believe that this issue is too small to deal with‚ but if the acid rain problem is not met with head on‚ the effects on people‚ plants‚ animals‚ and the
Premium Air pollution Acid rain Sulfur dioxide
Acid rain is a common term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture to produce a rain‚ snow‚ or hail of sulfuric and nitric acids. Such pollution may also be suspended in a fog‚ or the pollutants may be deposited in dry form. Environmental damage from acid rain has been reported in northern Europe and North America. High levels of acid rain have also been detected in other areas of the world‚ such as above the tropical rain forest of Africa. Acid rain
