Acid dissociation constant

to full but you still want to eat just eat a little copper sulfate which was used as an agent that makes you vomit also known as an emetic. CuSO4 can burn but there is no worry of it igniting. Also CuSO4 will not explode. When CuSO4 is mixed in with acid the CuSO4 will dissolve. Copper sulfate will cause eye irritation, but if left by your eyes for a long period of time it will cause significant damage to your eyes. If you inhale the dust you will have severe throat irritation. If CuSO4 is…

adsorbate (mg L–1), and b is a constant which reveals the affinity of binding sites (L mg-1). From the plots between (Ce/qe ) and Ce the slope (1/qm ) and the intercept (1/ qmb) can be calculated. The Langmuir constant used to calculate the suitability of the adsorbent to adsorbate by using dimensionless factor RL by: (5) 0 1 designated un-favorable and RL = 1 be a sign of linear and RL = 0 point out as irreversible adsorption. Adsorption constants and correlation coefficients…

12 mL of concentrated sulfuric acid, H2SO4 with caution, and shake the tube gently to moisten the sample with the appropriate acid. Connect the Exhaust system with the tubes which has been placed on the rack and ensure the aspirator system to start functioning. The rack and Exhaust system are locked to heaters block digester DS6 which has been preheated to 420 ̊C to begin the process of acid digestion. After about 5 minutes, turn off the aspirator system until acid fumes can be formed only in the…

sunflower and rice bran oils, the emulsification activity of biosurfactants. Pseudomonas aeruginosa had higher emulsification activity than Saccharomyces cerevisiae. While checking the sugar and lipid content in biosurfactants by phenol sulphuric acid method and vanillin reagent method, found high in Pseudomonas aeruginosa than Saccharomyces cerevisiae. Under this study, after centrigugation of crude extract,the pellets were suspended in a 40 mL of dichloromethane in a separating funnel and…

Figure 1 shows the relation between density ρ and molar volume Mv as a function of copper oxide. From this figure, can be observed that the ρ and Mv decreased with the increased of copper oxide content replacement the lead oxide. The decrease of density due to the molecular weight of CuO is lower than the molecular weight of Pb3O4. The decrease of the molar volume due to the decrease the number of oxygen and may be the ionic radius of copper ions less than the ionic radius of lead ions. The…

15mol/L sodium thiosulphate solution (Na2S2O3) and 3mol/L hydrochloric acid (HCL) were poured into two separate 50 ml beakers, and the two beakers were transported to the experimental table for convenience. 5. 25 ml of 0.15mol/L sodium thiosulphate solution were measured in a 25 ml measuring cylinder. Pipette was used to transfer the solution from beaker to the measuring cylinder for accuracy. 6. 4 ml of 3 mol/L hydrochloric acid were measured in a 10 ml…

Normal standards for specific gravity are as typically as follows: 1.000 to 1.030 is a normal specific gravity, 1.001 after drinking excessive amounts of water, more than 1.030 after not drinking very many fluids and concentrated after receiving an antidiuretic hormone (ADH). Max’s urine concentration varied in concentration each time he was tested. The first test showed that his urine was a pale yellow which was an indication that he was hydrated. The second test showed the concentration to be…

Introduction Density measures the volume that a given amount of mass takes up. Usually, density has grams per unit volume as a unit. To find the density of an object, the object has to be measured and its mass has to be divided by its volume. Often times, density is used to identify substances, since different elements have specific densities. This experiment is made up of two sections; the first section measures the density of water and the density of an unknown substance. If the procedure is…

The objective of this experiment in Lab #2 was to identify an unknown substance using different chemical tests to determine what organic molecules it contains. These tests are referred to as the Benedict’s, Lugol’s, Biuret, and Sudan IV tests and are each used to identify an organic compound. For instance, Benedict’s checks for reducing sugars, Lugol’s for starch, Biuret for protein, and Sudan IV for lipids. When testing the unknown with each reagent, the substance only tested positive for…
