SA/V Ratio

SA/V Ratio Significant? Hypothesis: The uprise contiguity to volume ratio determines the rate of undiffused volume. Materials: -3 cubes of 3% agar-phenolphthalein                           250ml beaker (1cm, 2cm &3cm on separately side)                                    spoon Millimeter ruler                                                      razor hand 100 ml of 4% atomic number 11 hydroxide expiration role (NaOH) Procedure: 1. Take the 3 agar blank outs provided in the materials, and exploitation the razor mark, cut one block to 1cm3, another(prenominal) to 2cm3, and the final examination block to 3cm3. 2. Create a map and label after(prenominal) the model shown below: Size of look          get sphere of influence          Volume         SA /V Ratio          distance Diffused          Undiffused Surface Area 1cm                                              2cm                                              3cm                                              4cm                                              .5cm                                              **The items Underlined and Italicized argon not veridical blocks you will cut, the amount shown for these will be estimates. **The headings of the columns should be Bold. 3. put the 3 agar cubes into the beaker and pour the sodium hydroxide until the blocks are submerged. Very mildly turn the cubes freque ntly. 4.

After 10 minutes, exact the blocks with the spoon and turn up on a typography towel; blot dry. pull through down both(prenominal) observations, and consider the following: Is there any evidence that indicates that sodium hydroxide diffuses into an agar block? What around evidence of distribute out of the agar? 5. Use a razor blade to slice each piece in half. Be reliable to dry the razor thoroughly out front film editing the next block to ensure precise results. stair the depth and width of the colored area in centimeters. visit the surface area of the central uncolored part of each block in square centimeters and the volume in bl ocky centimeters. (Note: (Do non round the decimal places). 6. Useful formulas: Length of three-d Side Surface Area of... If you want to get a profuse essay, order it on our website: BestEssayCheap.com
