In an experiment, a solution of AgNO3 was added to known solutions of NaCl, NaBr, and NaI and each reaction formed a precipitate. When chlorine water and hexane were added to these known samples, the hexane layer showed no color for NaCl, turned orange for NaBr, and turned purple for NaI. The observations for your unknown are listed below. Which ion is your unknown? UNKNOWN # 98 Experiment Observations TEST 1 Add AgNO3 Off-white ppt TEST 2 Add BaCl2 reaction does not occur TEST 3 Add dilute HCl reaction does not occur TEST 4 Add chlorine water & hexane orange top layer Group of answer choices chloride bromide iodide none of the above
CALCIUM PEROXIDE OCTAHYDRATE (CaO2.8H2O) SYNTHESIS CaCO3 + 2 HCl --> CaCl2 + CO2 + H2OCaCl2 + 2 NH3 + H2O2 + 8 H2O --> CaO2.8H2O + 2 NH4+ + Cl- Question: Calculate the percentage yield of the product you have obtained.(just find the theoritical value) procedure: 5 g of pure CaCO3 is added in small portions to 10 mL of water and 20 mL of 18% HCl in a 100 mL beaker and mixed with a bottle. During this process, the mixture should be boiled in order to remove the CO2 formed. When the CaCO3 addition is complete, it is observed that a sufficient amount of precipitate is formed at the bottom of the container. The solution is filtered while hot, the excess water is evaporated and cooled with ice water. Thereupon, he says 25-30 mL of 6% H2O2 solution, 5 mL. NH3 and 100 mL water are gradually added with stirring. After stirring for a while, the crystals formed are filtered, washed several times with water and dried in a desiccator.!(Work in a 1: 4 ratio.)!
