Free Essays on The Killing Game

â€Å"The killing game† Before reading â€Å"The killing game† by Joy Williams, I considered myself a â€Å"non-hunter†. However, after reading â€Å"The killing game†, I had mixed feelings of how I felt about hunting. I think Williams unjustly stereotyped all hunters as being â€Å"immoral† without consideration for another point of view. I decided to look equally at both sides of this issue to determine which side, â€Å"non-hunter† or â€Å"anti-hunter†, I would support. I interviewed my friend, Dona Mayo, about hunting. I believed that she would know about hunting since she had hunted in the past and her father is an active hunter. She considers herself to be a â€Å"non-hunter† now but does support the rights of a limited amount of hunting for appropriate reasons. Her family always takes home and eats all the animals they kill. Any left over meat is donated to church or given to other families. Every edible part of the animal is eaten. The head is kept as a trophy if it has a good rack. They prefer to hunt deer, turkey and squirrel. At one point, in 1985 lots of people were laid off from work. They had to rely on hunting to supply them with meat when they could no longer afford to buy any. She did have a friend of hers that was involved in a hunting related accident. His name was Chris, when he was thirteen he had accidentally shot and killed his father by laying a gun that had a bullet lodged in the rifle while climbing a fence. It is illegal to hunt in state parks in Mississippi. Taxpayers pay extra for license to hunt in preserves, and the money hunters pay go towards the parks. She believes hunting illegally in parks should have license revoked, and pay fines and/or jail time. I finally asked Ms. Mayo how she felt of the comment from â€Å"The killing game†; â€Å"Sport hunting is immoral; it should be made illegal. Hunters are persecutors of nature who should be prosecuted.† She respon...

How to Calculate the pH of a Weak Acid

How to Calculate the pH of a Weak Acid Calculating the pH of a weak acid is a bit more complicated than determining the pH of a strong acid because weak acids dont completely dissociate in water. Fortunately, the formula for calculating pH is simple. Heres what you do. Key Takeaways: pH of a Weak Acid Finding the pH of a weak acid is a bit more complicated than finding pH of a strong acid because the acid does not fully dissociate into its ions.The pH equation is still the same (pH -log[H]), but you need to use the acid dissociation constant (Ka) to find [H].There are two main methods of solving for hydrogen ion concentration. One involves the quadratic equation. The other assumes the weak acid barely dissociates in water and approximates the pH. Which one you choose depends on how accurate you need the answer to be. For homework, use the quadratic equation. For a quick estimate in the lab, use the approximation. pH of a Weak Acid Problem What is the pH of a 0.01 M benzoic acid solution? Given: benzoic acid Ka 6.5 x 10-5 Solution Benzoic acid dissociates in water as: C6H5COOH → H C6H5COO- The formula for Ka is: Ka [H][B-]/[HB] where:[H] concentration of H ions[B-] concentration of conjugate base ions[HB] concentration of undissociated acid moleculesfor a reaction HB → H B- Benzoic acid dissociates one H ion for every C6H5COO- ion, so [H] [C6H5COO-]. Let x represent the concentration of H that dissociates from HB, then [HB] C - x where C is the initial concentration. Enter these values into the Ka equation: Ka x  · x / (C -x)Ka x ²/(C - x)(C - x)Ka x ²x ² CKa - xKax ² Kax - CKa 0 Solve for x using the quadratic equation: x [-b  ± (b ² - 4ac) ½]/2a x [-Ka (Ka ² 4CKa) ½]/2 **Note** Technically, there are two solutions for x. Since x represents a concentration of ions in solution, the value for x cannot be negative. Enter values for Ka and C: Ka 6.5 x 10-5C 0.01 M x {-6.5 x 10-5 [(6.5 x 10-5) ² 4(0.01)(6.5 x 10-5)] ½}/2x (-6.5 x 10-5 1.6 x 10-3)/2x (1.5 x 10-3)/2x 7.7 x 10-4 Find pH: pH -log[H] pH -log(x)pH -log(7.7 x 10-4)pH -(-3.11)pH 3.11 Answer The pH of a 0.01 M benzoic acid solution is 3.11. Solution: Quick and Dirty Method to Find Weak Acid pH Most weak acids barely dissociate in solution. In this solution we found the acid only dissociated by 7.7 x 10-4 M. The original concentration was 1 x 10-2 or 770 times stronger than the dissociated ion concentration. Values for C - x then, would be very close to C to seem unchanged. If we substitute C for (C - x) in the Ka equation, Ka x ²/(C - x)Ka x ²/C With this, there is no need to use the quadratic equation to solve for x: x ² Ka ·C x ² (6.5 x 10-5)(0.01)x ² 6.5 x 10-7x 8.06 x 10-4 Find pH pH -log[H] pH -log(x)pH -log(8.06 x 10-4)pH -(-3.09)pH 3.09 Note the two answers are nearly identical with only 0.02 difference. Also notice the difference between the first methods x and the second methods x is only 0.000036 M. For most laboratory situations, the second method is good enough and much simpler. Check your work before reporting a value. The pH of a weak acid should be less than 7 (not neutral) and its usually less than the value for a strong acid. Note there are exceptions. For example, the pH of hydrochloric acid is 3.01 for a 1 mM solution, while the pH of hydrofluoric acid is also low, with a value of 3.27 for a 1 mM solution. Sources Bates, Roger G. (1973).
