1. In general‚ solubility rules can be used to predict the outcome of double replacement reactions. I have come to this decision‚ because almost all of the data recorded from the lab‚ with the exception of number 13‚ agreed with the predictions made beforehand. 2. Out of the 15 combinations‚ the observations made for the combination of number 13 (the reaction of lead (II) nitrate and barium chloride)‚ did not agree with what was predicted‚ based on the solubility rules. The solubility rules

INVESTIGATE FACTORS INFLUENCING THE SOLUBILITY OF SALTS Research question How does temperature affect the dissolving time of various salts.? Hypothesis I predict that with water of high temperature the salts will dissolve quicker. Controlled Variable Amount of water (solvent) Amount of salt used (solute) Type of cups taken and their sizes Independent variable Temperature of water Dependent variable Time taken for each salt to dissolve Material Required Measuring

This experiment contains three separate procedures in which Aluminum Potassium Sulfate(Alum) will be melted‚ massed out and mixed with Barium Nitrate‚ along with distilled Water. Procedure one we completed two trials of melting two separate 0.01g of Alum and making a comparison to the literature temperature of 92.5‚ to do this we attached an Alum filled capillary tube to a thermometer and inside a beaker placed over a Bunsen burner. Procedure two consisted of placing 2.00 grams of Alum into a crucible

PREPARATION OF POTASH ALUM [(K2SO4.Al2(SO4)3.24(H2O) Aim: To prepare a pure sample of potash alum. [K2SO4.Al2(SO4)3.24H2O] Principle: Potash alum is prepared by dissolving an equi molar mixture of aluminum sulphate and potassium sulphate in minimum amount of water containing a little amount of sulphuric acid and then subjecting the solution to crystallisation; octahedral crystals of potash alum separate out. Apparatus required: Beaker (100 ml) Trough Funnel Wire gauze Conical

For this experiment me and my lab partner didn’t finish the experiment. We only end up to adding the magnesium sulfate. We added so much magnesium sulfate‚ and ended up drying the whole product without any liquid left. We were trying to do the procedure all over again but‚ we will ended up to not finishing the experiment still due to time constrain. I will try to explain the possibility what will happen up to the end of the experiment. After measuring the 10ml graduated cylinder‚ which is 27.27g

Experiment #3 Mark A. Bruder 07. T.A. Michael Hall Alkanes: Chlorination Introduction: The purpose of this experiment is to determine the reactivity of hydrogen atoms on a carbon chain using free radical chlorination. In this experiment 1-chlorobutane will be chlorinated with the combination of sulfuryl chloride and ABCN as an initiator to produce the chlorine radicals. The combination of 1-chlorobutane and sulfur chloride will produce four dichlorobutane

The mean data observed show a number of trends. The average weight and length tend to decrease as the amount of Ammonium Sulfate approaches the full recommended dose. On the other hand‚ the average amount of protein per gram of tissue tends to increase as the amount of Ammonium Sulfate approaches the full recommended dose. Our null hypothesis was that there is no difference between the mean weights or the mean lengths of the seedlings two different treatments. (A+B‚ A+C‚ and B+C) Each of these
