Jell-O Lab Guiding Question: Are some laundry detergents better than others? Purpose: We intend to test if the cost of a detergent affects its quality but putting 3 drops of Jell-O into 25mL of Jell-O and examining how much of the Jell-O dissolves. Hypothesis: If the cost of the detergent increases‚ then the amount of Jell-O dissolved will increase by 0.3 cm. Materials/Equipments: * 4-1mL Pipettes * 5cm long standard drinking straw with a diameter of .6cm. * Jell-O brand

Soaps used for cleaning purpose are sodium or potassium salts of long chain fatty acids‚ e.g.‚ stearic‚ oleic and palmitic acids. Soaps containing sodium salts are formed by heating fat (i.e.‚ glyceryl ester of fatty acid) with

Gel filtration chromatography on Sephadex G-50 The crude broth obtained after fermentation was subjected to ammonium sulphate precipitation at 70% (w/v). The pellet so obtained was resuspended in cold saline (2 ml) and dialysed. The dialysed enzyme was loaded onto a column of Sephadex G-50 (120 cm × 1.0 cm) equilibrated with 10 mM Tris-HCl buffer‚ pH 8. The column was eluted at a flow rate of 1 ml / 6 min. The elution profile of gel filtration chromatography is shown in the (Fig: 1). The fractions

Discussion: 6. The ph solutions that were used were 2‚4‚7‚9 and 10. All of these solutions affected the beetroot‚ but the most acidic solutions were the ones that did the most damage to the membrane. This is because the ph affects the proteins within the phospho lipid bi-layer. The acidic ph breaks the hydrogen bonds therefore denaturing the proteins and allowing beetroot pigment to secrete form the cell. 7. The ethanol solutions that were used were 11%‚ 25% and 50% ethanol. The beetroot cell

Sulfination Units Sulfination is the introduction of sulfonic acid into an organic compound. The usual sulfinating agent or sulficant is concentrated sulfuric acid but‚ sulfurtrioxide‚ chlorosulfonic acid‚ metallic sulfates‚ and sulfamic acid are also occasionally used. The name sulficants comes from these molecules moving to the surface of a liquid or to an interface between two liquids and changing the properties of the surface. However‚ the nature and properties of sulfuric acid‚ makes it

Knowing how to wash clothes —without ruining them — is a basic life skill. Before you load up the washing machine‚ you have to do some prep work such as separating items by color and texture‚ choosing the right washing cycle‚ and knowing how much detergent to add. All this calls for just a little practice‚ but you’ll get the hang of it in no time. Separate and divide for laundry success Not all fabrics are made the same‚ so you need to create piles of items based on color and fabric type: Separate

Our objective is to determine what the milk and colors will look like after adding the soap. Hypothesis: After preforming the lab one time through‚ we are able to hypothesize about what could happen when we change different factors
