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

What is acid rain? Rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm‚ typically to forests and lakes. What chemicals make rain acidic‚ and how does it happen? Besides water‚ and carbonic acid (from carbon dioxide dissolved in the rain droplets)‚ the primary components of acid rain are sulfuric acid‚ which comes from sulfur dioxide derived from the burning of coal‚ and nitric acid‚ which from nitrogen emissions. Where do these chemical come from? These

Acid rain is rain that has become acidic‚ because of air pollutants in the atmosphere. Rain has a normal pH level of around 5-5.5 which is only slightly acidic. 7 on the pH scale is the neutral and anything below that is considered acidic. Acid rain has a pH level around 4 which is 10 times more acidic. Acid rain can fall in many different ways and has many effects on the environment. Acid rain is caused by air pollutants in the atmosphere. These air pollutants are mainly from man made resources

Titration Lab How Much Citric Acid is in Your Soda? PURPOSE To determine the molarity (concentration) of citric acid (H3C6H5O7) in various different citrus flavored sodas. BACKGROUND PRINCIPLES Popular sodas all strive for a somewhat sour (’tart’) flavor and manufacturers utilize acids to impart this taste. While there are a vast variety of different brands of sodas on the market‚ they can be broken into two main categories: dark or clear. This differentiation is not only a simple color

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

Acidification: From Nutmeg to Trimyrisitin to Sodium Myristate to Myrisitic Acid Mandy Boyle Chem 213‚ Section 002 Due Date: December 3‚ 2009 I. Introduction People encounter esters everyday in both natural and synthesized forms. Esters are present in a variety of common compounds‚ from fragrances to animal fat (McMurry‚ 2008). Although these esters can undergo many different important reactions‚ this lab is particularly interested in the hydrolysis of esters into carboxylic acids and alcohols

Essay March 28‚ 2014 ACID RAIN ENVIRONMENAL EFFECTS What is acid rain? It’s a rain or any other form of precipitation that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide‚ which react with the water molecules in the atmosphere to produce acids. The most obvious environmental effect of acid rain has been the loss

A buffer is an aqueous solution that allows resistance to significant change in pH when small amounts of strong acids or base are added to it. (Boundless‚ 2015) This is usually formed when a weak acid is added to a salt of its conjugate base. (Chemicool.com‚ 2014) When an Alka Seltzer tablet is dissolved in water‚ a buffer is formed when the weak acid citric acid is present with sodium citrate (citrate ion) the conjugate base (Buffer Balancing Acts Buffers‚ 2009) "Na3C3H5O7 (aq) + 3 HCl (aq)
