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

Recrystallization of Benzoic Acid Objective To purify benzoic acid by recrystallization and gain experience with a basic organic laboratory techniques. Background Products of chemical reactions are often contaminated with impurities. One method for purifying chemicals‚ recrystallization‚ takes advantage of the differences in the solubilities of the desired products and the impurities and the tendency for the slow formation of crystals to exclude impurities from the crystalline solid.

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

involve the reaction of an acid and a base to produce a salt (ionic compound) and water. Acid + Base ( Salt + Water □ In this lab‚ sulfamic acid (a weak acid which contains one acidic hydrogen) will be used: H2NSO2OH(aq) + NaOH(aq) ( NaOSO2NH2(aq) + H2O(l) (Net Equation: H+(aq) + OH-(aq) ( H2O(l)) □ Titration is a process of neutralization □ Titration is commonly used to determine the concentration of an acid or base in a solution.

Investigating the effects of acid rain in the growth of cress seedlings IntroductionAcid rain is rain or any other form of precipitation‚ which is unusually acidic. It has harmful effects on plants‚ animals and buildings. Acid rain is mostly caused by human emissions of sulphur and nitrogen compounds which react in the atmosphere to produce acids. Acid rain can slow the growth of vulnerable forests and cause leaves and needles to turn brown and fall off. In addition‚ it depletes minerals from the

Acid: A chemical substance (typically‚ a corrosive or sour-tasting liquid) that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red. Ionic Dissociation: Dissociation in chemistry and biochemistry is a general process in which ionic compounds (complexes‚ or salts) separate or split into smaller particles‚ ions‚ or radicals‚ usually in a reversible manner. Strength of Acids: The strength of an acid refers to its ability or tendency to lose a proton. There are very few strong acids. A
