Acid Rain and its Chemistry Acid rain is a type of pollution that is becoming a major threat to our planet and is need of attention. Acid rain has significantly increased ever since the industrial revolution‚ and now around the world‚ countries like Russia‚ China‚ and those in Europe are facing increasing levels of acidity in their rain. Not only is it becoming more acidic but it is also spreading by the pumping of sulfuric gasses deeper into the atmosphere from of the use of taller smokestacks

Acid Rain Definition: The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852‚ when the English chemist Robert Agnus invented the term. From then until now‚ acid rain has been an issue of intense debate among scientists and policy makers. Acid rain‚ one of the most important environmental problems of all‚ cannot be seen. The invisible gases that cause acid

The Effects of Acid Rain Bio-105 Abstract The effects of acid rain is damaging no matter how you look at the picture. Acid rain effects open areas more than forests due to the trees blocking some of the rain from hitting the ground. Acid rain is monitored by using emissions monitors. This helps figure out how much acid is in rainwater. Acid rain is harmful to fish by killing off entire species. Acid rain is harmful to living creatures‚ but many do not realize how toxic it can be to

Worksheet - Acids‚ Bases and Salts 1. I am pure water. When heated my pH (increases‚ decreases)‚ because more of my water molecules dissociate. 2. I am a 0.020 M solution of weak acid‚ HA. If I only dissociate to the extent of 1.50%‚ what is the value of my Ka? 3. I am a 0.20 M solution of hydrocyanic acid‚ HCN‚ with a Ka of 4.93 x 10¯ 10 . What is my pH? 4. I am a buffer made from 0.10 M acetic acid and 0.15 M sodium acetate. If the Ka for acetic acid is 1.77 x 10¯ 5 ‚ what is my pH? 5. I am

Experiment # 3 Acetylsalicylic Acid Introduction: The purpose of this experiment is to create and isolate pure acetylsalicylic acid from the substances salicylic acid and acetic anhydride. Then one will find the melting point to determine purity. Procedure: Make a hot bath. Weigh some salicylic acid and place in conical vial. Add .480mL of acetic anhydride and a drop of concentrated phosphoric acid. Drop in a magnetic spin vane and attach air condenser to vial. Partially submerge it in

white solution can be put in 60⁰C and 80⁰C water bath to test for how temperature affects denaturation. It can be record by the time need for the first change of appearance. To find out how pH of affect denaturation‚ we can add dropwise the actetic acid to the egg white solution. Beside‚ the NaCl can also be add dropwise to egg white‚ to test for how salt concentration cause denaturation. Count the number of drop of solution added for an appearance change to occur. Observation: |60 ⁰C water bath
