A solution of cobalt(II) chloride is analyzed, and the concentration of cobalt(II) ions is found to be 0.27 mol/L. What is the expected concentration of chloride ions?
Record only your numerical answer with the correct number of significant digits. You do not need to include units as the units appear for you beside the answer box already.
You perform your first titration using your NaOH with a KHP solution. Your KHP solution is made with 0.5045 g of KHP. The initial amount of NaOH in your pipette is 16.26 mL and the final amount in your buret is 36.79 mL when the indicator changes colour. Determine the concentration of your NaOH solution. Write your answer to four decimal places without units.
Sodium carbonate dissociates when it dissolves in water as follows:

In other words, why do we have to standardize the NaOH in this experiment to find its exact concentration?(Hint: think about the glassware used and refer back to the worksheet on glassware at the beginning of the semester.)arrow_forwardSolubility is the ability to dissolve certain substances(solutes) into a solvent. You are a student in Mrs. Bateast's Chemistry class and you were given the assignment to compare solubilities of salt in different solvents at different temperatures. You added salt at a consistent rate and amount until you reached the point of full saturation. The amount added to each solvent at saturation was recorded. The results of the experiment are shown in the tables: Table 1: 20 °C Mass of Salt at Saturation 43 g 38 g 0.01 g 3 g Solvent Water Ethanol Hexane Dichloromethane Table 2: 35 °C Mass of Salt at Saturation 52 g 45 g 0.02 g 4 g Solvent Water Ethanol Нехane Dichloromethane Using CER and your knowledge from data listed above, if the temperature of ethanol solution increased by an additional 10 degrees, what would happen?

What effect would this have on the measured volume of hydrogen gas? Would the calculated molar volume of hydrogen gas be too high or too low as a result of this error? Explain. 2. A student noticed that the magnesium ribbon appeared to be oxidized—the metal surface was black and dull rather than silver and shiny.
