Simple qualitative analysis involves the identification of the constituents of an inorganic substance or a mixture of substances. The inorganic substances are split-up into two types of charged particles one of which is positively charged and the other is negatively charged. The charged particles are called ions or radicals. The positively charged ions are called cation or basic radical. The negatively charged ion is called anion or acid radical. In the qualitative analysis of an inorganic

OBJECTIVES : To compare the final product of two different method and ingredient and investigate the factor contributed with the final product’s appearance. EVALUATIONS TREATMENT 1 Fine texture‚ smooth‚ and even pores Thin crust TREATMENT 2 Has tunnel at the centre‚ dark brown. Soggy Thick‚ Tough and harden DISCUSSIONS Chocolate cake from first recipe gives great texture of crumb and crust of the cake. In contrast‚ the second cake give a worse texture of the crumb

After conducting the trials for each beaker and each bag my hypothesis of each of the trials were correct. Every outcome I predicted occurred to each beaker and each bag. Beakers 1 and 2 decreased in mass while beaker 3 stayed constant. Beaker 4 actually increased in mass as well. Bags 1 and 2 increased in mass while bag 3 stayed the same. Bag 4 resulted in a decrease in mass. The results I got from this experiment do support what I predicted before the trials. Above you can see a specimen of an

After distributing the Stroop Task‚ the following results were discovered: the mean for the musicians was 1178.7070 milliseconds and the total mean for the athletes was 1235.188 milliseconds. Our results was the following‚ t(18)=0.587; p=0.567. The results as demonstrated can clearly state that there was not a significance within the .05 alpha level. Therefore‚ the null hypothesis had to be retained. Our conclusion of the Stroop Task was that the musicians did not show a faster (lower) time in comparison

10 Test Tube Mystery Introduction: The students were handed 10 test tubes with no identification. The students were supposed to design a method in determining what chemical was in each test tube. The list of chemicals is CuSO4‚ NH4Cl‚ NaOH‚ AgNO3‚ KI‚ H2SO4‚ NaBr‚ CaCl2‚ HCl‚ and Pb(NO3)2. The students are expected to determine the chemicals using physical properties‚ litmus paper‚ solubility‚ and the process of elimination. Physical properties‚ such as the color‚ can be determined by sight. Litmus

In this lab‚ we tested the effect of flame on different chemical solutions. In order to do this‚ we used a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition

VARIOUS LAB TEST ON CEMENT: Checking of materials is an essential part of civil engineering as the life of structure is dependent on the quality of material used. Following are the tests to be conducted to judge the quality of cement. 1. Fineness 2. Soundness 3. Consistency 4. Initial and Final Setting Time of Cement FINENESS OF CEMENT: We need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement

overall? Background: Past tests of the highest quality paper towel showed that Bounty was the best choice for a kitchen paper towel. Although it wasn’t the most absorbent‚ which was Brawny‚ it was rather strong in both durability and absorbency. (consumerreports.org) Industrial and 7th generation are most commonly used in public places such as; School bathrooms‚ public restrooms and public sinks. 7th generation is made of 100% recycled paper. In another test‚ between Viva and 7th generation
