Design an experiment‚ based on the principles of diffusion and osmosis‚ that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer: a. a description of how you would set up and perform the experiment; b. the results you would expect from your experiment; and c. an explanation of those results based on the principles involved.

to be relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). Preparation It is manufactured by the calcium process: ~\mathrm{2Cl_2 + 2Ca(OH)_2\longrightarrow \ Ca(OCl)_2 + CaCl_2 + 2H_2O}. "Bleaching powder" is a mixture of calcium hypochlorite (Ca(OCl)2) and the basic chloride CaCl2‚ H2O with some slaked lime‚ Ca(OH)2. Properties Calcium hypochlorite is a yellow white solid which has a strong smell of chlorine. It is not highly soluble in water

Guajillo powder is made up of ground guajillo chiles‚ which are another popular variety of Mexican chile pepper. As with other Mexican chiles like the ancho chile‚ the fresh form of the guajillo chile has a different name. When fresh‚ the guajillo chiles used to make guajillo powder are called mirasol chiles. Mirasol means looking at the sun and refers to the fact that the peppers often grow pointing straight up. When dried‚ the seeds of these peppers make a rattling sound when they are shaken. That

effect of pH on amylase activity Aim The aim of the experiment is to determine the effects of different pH and the rate of reaction on fungal amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which is the bodies normal

Email: femijohn@gmail.com 43 INTRODUCTION The roles of metal ions in metalloenzymes include direct participation in catalysis‚ stabilization of protein structure and regulation of enzymatic activity. Membrane alkaline phosphatase (ALP) is a metal-containing enzyme that serves as a good model for the study of metal ion interactions in enzyme catalysis. Native E. coli ALP contains three

Powder metallurgy is the process of blending fine powdered materials‚ pressing them into a desired shape or form (compacting)‚ and then heating the compressed material in a controlled atmosphere to bond the material (sintering). The powder metallurgy process generally consists of four basic steps: (1) powder manufacture‚ (2) powder blending‚(3) compacting‚ (4) sintering. Compacting is generally performed at room temperature‚ and the elevated-temperature process of sintering is usually conducted at

Dish Washing I walk into the restaurant Red Robin‚ wait for my name to be called by the host and sit down in a booth with comfortable red seats. All of a sudden a man sits next to me wearing an apron soaking with water‚ wiping sweat from his face. It’s my brother‚ Zachary Walsh. Zach states “ Man‚ I hate Saturday nights‚ too damn busy!”. What was Zach doing? Zach is a dish machine operator‚ or in restaurant terms‚ a DMO. Washing dishes you say‚ that sounds easy! I am afraid not my friends. Washing
