Find the Final volume of buret (mL) and the Concentration of NaOH (M )

CHM 17 Experiment #8   CONCENTRATION OF A SOLUTION   Discussion   This virtual experiment involves the determination of the conc­entration of salt (sodium chloride, NaCl) in an aqueous solution.  Concentration may be expressed many ways, and this experiment studies two systems: molarity (M) and weight/volume percent (%w/v).   Molarity is defined as the number of moles of solute (in this case NaCl) in a liter of solution. It is calculated with the following equation:                                                   M = moles solute                                                                 liters solution                                      Percent concentration (w/v) is defined as the number of grams of solute (in this case NaCl) in 100. mL of solution. It is calculated with the following equation:                                             %(w/v) =  grams solute  x  100                                                             mL solution   The experimental method…

Two students are studying the Arrhenius reaction below: NaOH + Hz S04 Na SOy + H2O base salt acid water Did the students identify the acid, base and salt correctly? If not, provide the correction. Paragraph BIU

Suppose a student performs a similar reaction using sodium bicarbonate (NaHCO3) instead of sodium carbonate. The sodium bicarbonate is dissolved in water, and a solution of 6.0 M HCl is added to the sodium bicarbonate in increments. Bubbles are observed during the reaction. The data collected is shown in the table. moles of NaHCO3: mass of empty beaker (g) moles of NaCl: mass of beaker and NaHCO3 (g) initial volume of 6.0 M HCl (mL) How many moles of NaHCO3 were used? balanced equation: final volume of 6.0 M (ml) mass of beaker and NaCl (g) How many moles of NaCl were produced by the reaction?

In a terrible accident, a solution consisting of 2.59 kg of nitric acid, HNO3, was spilled on the lab floor. Very quickly, you decide to throw 2.00 kg of sodium carbonate, Na2CO3, on the spilled acid. You then run out of the building due to the significant quantities of carbon dioxide that would form due to the reaction. As you stand outside, you wonder, "Did I add enough sodium carbonate to neutralize the acid?". a) Did you add enough sodium carbonate to neutralize the acid? Needed Yes b) In the event that you did not add enough sodium carbonate, how much extra would be needed to completely neutralize the acid? If you have added enough, please enter a value of 0 (zero). No Excess 80 g c) In the event that you did add enough sodium carbonate, how much extra did you add? If you didn't add any extra, please enter a value of 0 (zero). 80 g

Part C You need to prepare a 2.40 M solution of sodium hydroxide (molar mass of sodium hydroxide = 40.00 g/mol ), but you only have a 10 mL graduated cylinder and a 25 mL beaker.

Name Lab Partner Section # Date Pre-Lab Assignment: Stoichiometry Lab 1. In a lab experiment similar to the one you are going to do, a student slowly added hy- drochloric acid (HCI) to an evaporating dish containing magnesium carbonate MgCO3. a. Complete and balance the following equation for the reaction between magnesium carbonate and hydrochloric acid. MgCO3 (s) + HCl (aq) → (aq) + H₂CO3(aq) (When writing the formula for the missing product did you consider the charges of the ions?) b. When carbonic acid is formed in a chemical reaction, it is unstable and immedi- ately decomposes into carbon dioxide and water. Rewrite the equation above to show the final products using this information.

Macmillan Learning Experiment 1: Suppose a student repeats the experiment, but adds 25 g of sodium bicarbonate to the 6 M HC instead of adding 1 M NaOH. What observations indicate that a reaction took place? Bubbles formed in the solution after the sodium bicarbonate was added to the HCl in the Erlenmeyer flas The solution changed color after the sodium bicarbonate was added to the HCl in the Erlenmeyer flask. A reaction did not happen when the sodium bicarbonate was added to the HCl in the Erlenmeyer flask. The temperature decreased after the sodium bicarbonate was added to the HCl in the Erlenmeyer flask. A precipitate (solid) formed after the sodium bicarbonate was added to the HCl in the Erlenmeyer flask. The temperature increased after the sodium bicarbonate was added to the HCl in the Erlenmeyer flask.
