Apr 01, 2014 · Ammonia-ammonium chloride will also be prepared to be used as a buffer in the solution. The professor prepared the Erichrome black T to be used as an indicator. This indicator will be cause the solution to be red at the before the titration and then at the endpoint, the solution will turn blue. Aug 11, 2010 · In this catalase and hydrogen peroxide experiment, we will discover how enzymes act as catalysts by causing chemical reactions to occur more quickly within living things. Using a potato and hydrogen peroxide, we can observe how enzymes like catalase work to perform decomposition, or the breaking down, of other substances. Catalase works to ... Typically, they contain a simple sugar as the carbon and energy source, an inorganic nitrogen source, various mineral salts and if necessary growth factors (purified amino acids, vitamins, purines and pyrimidines).

Lab 5-1B: Properties of Acids and Bases (/2) Purpose: Summarize in 1-2 sentences what you hope to explore or find out in this lab, based on the pre-lab material provided. What we hope to explore in this lab is to find if and what happens to the pH indicators if we add A, B, C and D solutions to them.

Sep 24, 2016 · The three major buffer systems of our body are carbonic acid bicarbonate buffer system, phosphate buffer system and protein buffer system. The body's chemical buffer system consists of three individual buffers out of which the carbonic acid bicarbonate buffer is the most important. CARBONIC ACID BICARBONATE BUFFER Cellular respiration produces carbon dioxide as a waste product. This is ...

Refill the buret with the unknown acid solution to a volume just between 0.00 mL and 1.00 mL. Read the initial volume of the buret to ±0.01 mL and record the initial volume in the table below. Add about 15 mL of the acid to a 250 mL beaker. Read the volume of the buret after the addition to ±0.01 mL... There are lots of acid-base indicators you could use for your titration. Phenolphthalein is a good all around choice because it turns from colorless to colored (it is much easier for the human eye to distinguish than changes from one color to another) and because of the pH range over which it changes.
