Acids and Bases Shane Purpose- To study the relationship between pH and metabolism. 10/21/13 Materials- see attached Per. D Biology Procedure- see attached Data and Results- see attached Theory- PH stands for the power of hydrogen. People refer to the pH scale as a tool for finding out if a substance is acidic‚ basic‚ or neutral. This scale goes from zero to fourteen. The number seven is neutral. Any number higher than seven on this scale is basic. Any number lower is acidic

The purpose of this experiment is to separate a solution of an acidic and organic compound and purify its respective acidic product through the techniques of an acid base extraction‚ recrystallization‚ and use of Melt Temp (melting point range). The reaction of an unknown acid (3-chlorobenzoic acid) with diethyl and sodium hydroxide was observed‚ and the solution naturally separated into an aqueous and organic solution. The mixture of acid and organic solution was created and then separated through

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

Tall (Nature) In my family all four of them are short. My parents are about 5’5 and my sisters are about 5’3‚ while I am about 6’1. I don’t know where I get my height from‚ but when I look at my cousins from my dad’s side every single one of the guys are just about 6’0 or higher and the tallest being 6’6. I have about 30 male cousins on my dad’s side. Also my grandfather from my mom’s side is 6’1‚ so I guess I got some of the height from him also. I actually

Acid-Base Titrations A Titration of Potassium Hydroxide Phthalate and Sodium Hydroxide Hanna Piper Department of Chemistry‚ SUNY College at Brockport‚ Brockport‚ NY 14420 Chemistry 205.06 Abstract Titrations are used to find the molarity of an unknown solution. A titration begins with an analyte and titrant being used to measure the unknown molarity of the analyte. In the following experiment‚ sodium hydroxide was used as the titrant and potassium hydroxide phthalate was used as the

Most Progressive President During the Progressive Era‚The United States faced many problems that needed to be addressed which were unfair business‚ poor working conditions and destruction of the environment. Presidents Theodore Roosevelt‚ William Howard Taft and Woodrow Wilson worked to fix some of these problems. While all the Presidents worked to correct these problems during the Progressive Era‚ Woodrow Wilson was the most progressive president because he attacked big business’s‚ signed the act

Properties of Acids and Bases Diagram: A B C D E F Bromothymol Blue Universal Indicator Phenolphthalein Litmus Paper Analyze: 1) F‚ C‚ D‚ B‚ A‚ E 2) D is neutral because it turned to the colour of green when it came in contact with the indicator Bromothymol Blue. The acid or base is green between 6.0-7.6 pH. 3) Solution E is more alkaline (more basic) than solution A because when E came into contact with the indicator Bromothymol Blue it turned

Educational Planning Planning can be defined as “a process of taking decisions for future actions in order to achieve pre-determined objectives by optimum utilization of available resources in a limited time frame”. Thus a pre-condition for planning is the existence of certain objectives which need to be achieved and constraints in this respect are time and resources. Here resources include all the three types of resources namely physical(or material)‚ financial and human resources. It is said
