Chemistry A Rap 1 4/6/12 Acid and Base Report If someone were to ask the common teenager in the US‚ “What’s acid?” they would probably respond with something akin to “It’s that one drug that makes you see stuff that isn’t really there and just kinda makes you crazy”. And if that same someone was to ask that same teenager‚ “What’s a base?” their response would most likely have something to do with either baseball‚ or freeze-tag. The thing is‚ most people don’t really understand the most common

Objectives 1. To separate a mixture of an acid and a neutral compound into its component by extraction. 2. To determine the melting point and the yield of the benzoic acid and the unknown sample. 3. To determine the unknown sample whether is is Trimethylmethanol or 1‚2‚4‚5-Tetrachlorobenzene. Introduction Extraction is a process of transferring a solute from one solvent to another. It is usually used to separate one or more components from a mixture. Diethyl ether‚ dichloromethane

Indicators can be used to determine whether these substances are acidic‚ basic or neutral. Manufactured indicators are one type and the second type is natural indicators. Believe it or not‚ the majority of fruits‚ vegetables and flowers contain pigments which may be used as acid-base indicators. For example‚ Red cabbage contains within

Introduction to Acids Base chemistry Purpose How to determine the constant equilibrium of an acid‚ Ka? How to evaluate the concentration (M) of an acid? In “part A” experiment‚ we would test the PH of different concentration of acetic acid (a weak acid which partially dissociated in water) with a PH probe. After we got the PH‚ we could find out the concentration of H+ by applying the relationship pH = -log [H+]. Having the determined value of [H+] of a weak acid with a known molar concentration

Every solution has either has an acid or basic trait. The acid or basic trait in a solution are called pH level. pH is a scale that is used to determine if solution is acidic ‚basic‚ or neutral. During Living Environment class‚ we conducted a experiment that allowed us to measure the pH levels of 3 solutions. We were split into groups and each person had to bring a household solution from around the house. There certain materials that were needed to conduct the experiment .The following

Purdue CHM 321 – Fall 2012 TA: Scott Cole Section 1 September 4‚ 2012 Unknown Concentration: X.XX ± X.XX M (@95% confidence interval) (adapted from a report prepared by N. Skrynnikov‚ 2009) Abstract The concentration of an unknown acid (HA) solution was determined by titration with a standardized solution of sodium hydroxide. The standardization of NaOH was done by titration with a solid acid sample‚ potassium hydrogen phthalate (KHP)‚ and phenolphthalein
