cell membranes are discovered in this exercise. Background The following information is key for the interpretation of the results of this experiment 1. Neutral red is a vital stain. It stains cells without quickly killing them. Many biological stains kill living cells. 2. Neutral red goes through an obvious color change‚ from red at about pH 6.8 to yellow at pH 8.0. 3. A 1% solution of sodium bicarbonate has a pH of about 8.5. 4. Yeast cells have an internal pH that is slightly acidic (about

5: Photosynthesis Problem: If the leaf disks are treated in a way you know increases the net rate of photosynthesis‚ should they start to float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source‚ then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore‚ shining a red light source onto the leaf disks would cause them to absorb more

Silveira Date of Submission: September 25‚ 2013 Lab Section: CHE110L*Z Purpose The purpose of this experiment is to use two common laboratory methods to see how mixtures can be separated based on physical properties. Paper chromatography will be used to separate the dye colors from M&M candy to see which colors contain yellow #5. Gravimetric separation will be used to separate salt and sand from a mixture. Procedure The procedure for this lab can be found on pages 16 – 30 in “General Chemistry
