Discussion: There were some patterns that were noticeable during this experiment. It was noticed that all of the sprays with the metal potassium in them had turned the flame a light pink for a few seconds. The sprays that held the copper in them all turned the flame a vivid green colour‚ with some including green sparks also. Both of the sodium bottles turned the flame orange for a short time. Electrons orbit the nucleus of an atom in energy levels. If atoms are heated up to the point where the

3.1 Ex-vivo Evaluation of the Mucoadhesiveness of Synbiotics Mucoadhesive properties prolong the retention time of the bead’s dose in the targeted site the colon [23]‚ [50]. Since the dose is intended to colonic release‚ mucoadhesion parameters play a key role in the efficiency of the form. The beads remain longer in contact with colonic mucosa when they have more mucoadhesive property. As a result the probiotics will have enough time to get released from beads and colonize the colon [37]‚ [51]

amounts of glucose‚ amino acids‚ urea‚ and salts in urine. To test this we used different chemicals that would react with one of the four items above showing either a high concentration or low concentration within the urine. By using a solution called silver nitrate we could test whether or not salt was present in the urine. If the urine turned a cloudy white after adding the silver nitrate the urine had a high concentration of salt. To test for amino acid we used a chemical called biuret solution. If

In order to determine the acidity of certain substances‚ we used moist and dry pH paper (litmus tests)‚ and observed the results. First we used dry pH paper to test the acidity of household ammonia‚ and it turned yellow. According to the legend‚ this indicates a weak acid. This is‚ however‚ not accurate as the vapor of the household ammonia wasn’t able to react as strongly with the pH paper since it was dry. Then‚ we used moist DI water pH paper with the same substance‚ household ammonia‚ and it

OBJECTIVE The main objective of this experiment is to carry out qualitative analysis to identify metal cations in unknown solution 1. INTRODUCTION An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed

condition (listed from left to right in the table) ranged from: 19.6-59.2%‚ 11.8-76.0%‚ 25.0-92.3%‚ and 12.5-89.8%‚ respectively. From this‚ we can generally see how the data from each group is spread out across each ligation condition. Table 2. ANOVA test results. The p-value corresponding to the F-statistic is lower than 0.05‚ suggesting that one or more treatments are significantly different. We can see that the treatments that are significantly different are the 1:1 with stuffer and 2:1 without stuffer

DISCUSSION: Qualitative analysis is used to determine the presence of cations or anions present within a sample and their impurities. Information known‚ such as chemical and physical properties‚ about cations and anions can be used to determine what steps should be used to separate the sample into one‚ specific ion. Qualitative analysis involves forming and decomposing complex ions. Qualitative tests are very sensitive‚ allowing to detect a very small amount present in sample. Due to sensitivity
