In experiment 1 you prepared a solution of sodium carbonate. This means you dissolved solid Na2CO3 in water. Since this ionic compound dissolved in water, you now have only its ions swimming around in the solution. What are the aqueous ions in your solution of sodium carbonate?

The precipitate did not dissolve because sulfate ion is too weak a base. The amount of sulfate ion that reacts with the hydronium ion is too small to cause a shift in the equilibrium sufficient to dissolve a signiticant amount of the insoluble sulfate. In general, the anion of a precipitate must be a stronger base than fluoride ion in order for the precipitate to be dissolved by the addition of a strong acid. After the reactions with barium ion,...

Balance the equation for the reaction observed: _ Cu(s) + HNO3(aq) → Cu(NO3)2(aq) +_ NO2(g) + H2O(1) 3. Add 40 mL of 3.0 M NaOH (sodium hydroxide) to the solution in your beaker. Write the balanced equation for the reaction observed: 4. Add 2-3 boiling chips to your beaker and carefully heat the solution, while stirring with a stirring rod, just to the boiling point. (Do NOT boil. Have a low flame and keep the beaker well above the flame.)...

1.) 4.00 g of NaOH are dissolved in water to make 5.00 L of solution. What is the concentration of hydronium ions, [H3O+], in this solution? Express your answer with the appropriate units. 2.) If you wanted to determine how much KOH (potassium hydroxide; a strong base) was dissolved in water, you could titrate it with a known amount of KHP (potassium hydrogen phthalate; a weak acid) until a color change indicates that the base is completely neutralized. The molecular...

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...

Write out your separation scheme for this experiment. 1. Heat 75 mL of water to 90 °C in a 250-mL beaker. 2. While the water is being heated, place 250 mg of salicylic acid, 1 drop of 85% phosphoric acid and 0.5 mL of acetic anhydride in a test tube. Add a boiling chip to the mixture and gently shake it in order to mix the reactants. 3. Heat the tube in the beaker of water at 85 - 90...

Running the Reaction Add 0.100 g benzil and 0.30 mL 95% ethanol to a 3-mL conical vial. Place a spin vane in the vial and attach an air condenser. Heat the mixture with an aluminum block (90-100°C) while stirring until the benzil has dissolved (see inset in Tech- nique 6, Figure 6.1A). Using a 9-inch Pasteur pipette, add dropwise 0.25 mL of an aqueous potassium hydroxide solution' downward through the condenser into the...
