B. Determining the Composition of a Mixture of Sodium Chloride and Sodium Nitrate Partner I Prepare a solution of sodium chloride + sodium nitrate and indicator. Obtain a dropper bottle of potassium chromate (indicator) solution. To a clean and dry 125 mL Erlenmeyer flask, add about 40 mL of water and 8 drops of indicator solution. Weigh out approximately 0.05 grams of sodium chloride + sodium nitrate solid and record its exact mass. Dissolve the solid in the solution from step 1, stirring with a stirring rod to ensure complete dissolution. Determine and record the total mass of the Erlenmeyer flask and solution, noting the balance that you use to weigh. Rather than measuring the volume of silver nitrate solution added as in Part A, we will measure the mass of titrant added and make use of the weight-percentage concentration of silver nitrate in calculations. Prepare the silver nitrate solution. Obtain about 15 mL of 1.70% w/w silver nitrate solution in a 50 mL beaker. Designate a…

Please use the given data to find the y-value in the equation (y=114.14x-112.74).
In class we are learning about solubility, electrolytes both strong and weak. I totally get it. I just want to review how the notation of polar covalent soluble nonelectrolytes work. For example, Glucose as a solid being dropped in a water solution. Even though it is not ionic, it is very soluble and does not break up, so is not a electrolyte. Like an Ionic soluble, it does get hydrated. Thus , by thjs logic should it be notated like this? Glucose (s) >>>>>>>> Glucose (aq) ??? Or is there some other notation for sugar solution?
