pH and Chromatography Lab Report Kevin Rivera Biology Mr. Langley 2C 10/7/13 Introduction In this lab‚ of pH and Chromatography‚ in the pH aspect of the lab we are trying to figure out the pH level of certain chemicals by writing down of known solutions to find the type of unkown solution using pH standards. In the Chromatography‚ we are trying to separate the chemicals using water and a piece of paper. Methodology Materials: Safety Goggles pH indicator & pH indicator key

Egg Lab Write Up The purpose of this lab was to depicked the many properties of diffusion such as isotonic‚ hypotnonic‚ and hypertonic‚ so that students could have a clear visual example to go by for future refrences. We also did this to learn about selective permeability and osmosis. Our original hypothesis stated that the vinegar would react with the calcium in the shell to create CO2 bubbles. Note I said the original hypothesis as this experiment took coarse over a four day period‚ in which

Testable Question: When the body is in the squat position to normal while the time limit stays the same and how far you squat is the same‚ will the heart rate recover after returning to standing position in 10 seconds? Hypothesis: If the body moves back to normal position from squatting position while the time limit

Alexis Becker Pre-Lab Experiment 7 Avinash Pallagani Investigating Stoichiometry with sodium salts of carbonic acid 4/2/14 A summary of the concepts: The purpose of this lab is to better understand “stoichiometry”. We will be reacting sodium carbonate (NaHCO)3 and sodium carbonate (Na2CO3) with hydrochloric acid to produce sodium chloride‚ water‚ and carbon dioxide. The balanced chemical reaction looks like this: NaHCO3 + HCl = NaCl + H2O + CO2 CAUTION: Be especially

Solve each of the following problems. Show your solution. 1. A hydraulic lift office chair has its seat attached to a piston with an area of 11.2 cm2. The chair is raised by exerting force on another piston‚ with an area of 4.12 cm2. If a person sitting on the chair exerts a downward force of 219 N‚ what force needs to be exerted on the small piston to lift the seat? Answer: a= 11.2 cm2 A= 4.12 cm2 f= 219 N F= 80.56 N F= fA / a ;
