In order to find the formula of the copper chloride hydrate‚ we had to separate the compound to find the mass of water and copper. To begin this process‚ we evaporated the water and created an anhydrous compound‚ meaning we were left with only CuxCly. By calculating the weight of both the anhydrous and the hydrated compounds‚ we could conclude that the difference in the weights was the weight of the H2O. From this we were able to calculate the percent composition of CuxCly and H2O (see Calculations:

mass of calcium carbonate content?Calcium carbonate is a substance found in the eggshells giving them hardness and strength. It is essential to the commercial egg industry that the biggest possible amount of eggs reaches the market. Hence‚ as calcium carbonate reacts steadily with hydrochloric acid to produce carbon dioxide as well as two other substances‚ I investigated which type of an eggshell contains more calcium carbonate. This reaction cannot be used directly to titrate the calcium carbonate

Material and Methods * Osmosis : -thistle funnel tube -dialysis tubing sack -saturated NaCl w/food coloring -beaker with distilled H2O The experiments begins with the construction of a simple osmometer by obtaining pre-soaked length of tubing ‚opened and tied at the end. The tube is filled with saturated NaCl solution (with added food coloring) and the thistle is inserted in the dialysis tubing. The dialysis tubing is sealed to the thistle funnel with dental floss and placed in a beaker

Discussion/Conclusion In this experiment‚ t-pentyl chloride was synthesis by reacting concentrated hydrochloric acid using nucleophilic substitution sn1. In the substitution reaction the Hydrogen in HCl protonated the alcohol group in t-pentyl alcohol and turned it to a good leaving group (H2O). a tertiary carbon cation was formed. a nucleophilic attach of the negative Cl- attacked the carbon cation forming t-pentyl chloride [7]. As the reaction proceeded‚ extraction and distillation techniques

Preparation of Sodium Chloride through titration Abstract: acid-base titration is a technique commonly used to determine the moles of acid in a sample by adding a known volume of strong base of a known concentration. The strong base provides the hydroxide ion‚ to react quantitatively with the acid. The point at which the acid is completely and exactly consumed the known quantity of base is called the equivalence end point and is signalled by a colour change in the solution (end point). This colour

mass of calcium carbonate in eggshells. Introduction To avoid the breakage of eggs before reaching market‚ the eggshells needs to be as strong as possible. The strength of eggshells is mainly determined by the percentage of calcium carbonate in it. In order to monitor the quality of eggshells‚ the following experiment has to be done to determine the percentage of calcium carbonate in eggshells. In this experiment‚ back titration is used. First‚ excess acid is reacted with the calcium carbonate

mass of Calcium carbonate in an egg shell Aim: is to find and work out the percentage of calcium carbonate by mass in eggshells by using acid base “back titration” Introduction: Calcium Carbonate‚ CaCO₃‚ is a compound which is polymorphic and therefore means that it can be found in a variety of different objects or organisms. For example: Rocks (limestone‚calcite)‚ sea snail shells‚ Eggshells‚ pearls and many more. This investigation will focus on finding out the percentage mass of calcium carbonate
