Use the Quadratic Formula to determine x, the [H+] and [F-] concentration at equilibrium, for a 0.10 M solution of HF.

Then calculate and report the pH for this solution.

Finally compare the above result obtained from using the Quadratic Formula to the result we obtained in class from using the Approximation Method.
(When is "close enough" really NOT "close enough"?!)

2. What is the pH and [F–]eq in a 0.100 M solution of HF?      Ans. pH = 2.08; [F–] = 8.2×10–3 M 3. What would happen to the equilibrium [H3O+] and the pH of the solution if we suddenly added some solid NaF? (Remember, sodium salts are completely soluble in water. How will this change affect the equilibrium system? Which direction will the reaction shift to minimize the disturbance?) If we suddenly added some solid NaF the solution will...

2.) FeSCN2+ equilibrium concentration was found to be 3.20 x 10-5 M in a solution made by mixing 5.00 mL of 1.00 x 10-3 M Fe(NO3)3 with 5.00 mL of 1.00 x 10-3 M HSCN. The H+ concentration is maintained at 0.500 M at all times since the HSCN and Fe3+ solutions were prepared using 0.500 M HNO3 in place of distilled water. a. How many moles FeSCN2+ are present at equilibrium? b. How many moles each of Fe3+ and...

Problem 1: Relations among Useful Discrete Probability Distributions. A Bernoulli experiment consists of only one trial with two outcomes (success/failure) with probability of success p. The Bernoulli distribution is P (X = k) = pkq1-k, k=0,1 The sum of n independent Bernoulli trials forms a binomial experiment with parameters n and p. The binomial probability distribution provides a simple, easy-to-compute approximation with reasonable accuracy to hypergeometric distribution with parameters N, M and n when n/N is less than or equal...

T F 1. A p-value of .008 in hypothesis testing means there is only a .8% chance we could get such sample statistics from the population if the null hypothesis is as stated. Such an event is considered unlikely and we would reject the null hypothesis. T F 2. As a general rule in hypothesis testing, it is always safer to set up your alternate hypothesis with a greater-than or less-than orientation. _____3. If the level of significance is .02...

In this exercise, you will analyze the supply-demand equilibrium of a city under some special simplifying assumptions about land use. The assumptions are: (i) all dwellings must contain exactly 1,500 square feet of floor space, regardless of location, and (ii) apartment complexes must contain exactly 15,000 square feet of floor space per square block of land area. These land-use restrictions, which are imposed by a zoning authority, mean that dwelling sizes and building heights do not vary with distance to...

Assume that we are working with an aluminum alloy (k = 180 W/moC) triangular fin with a length, L = 5 cm, base thickness, b = 1 cm, a very large width, w = 1 m. The base of the fin is maintained at a temperature of T0 = 200oC (at the left boundary node). The fin is losing heat to the surrounding air/medium at T? = 25oC with a heat transfer coefficient of h = 15 W/m2oC. Using the...

Activity 1: Scientific Reports You may have heard the question “If a tree falls in a forest and no one is around to hear it, does it make a sound?” A similar question can be asked about experiments. “If a researcher performs an experiment and never publishes the result has science been performed?” Many people would say no because science is the accumulation of knowledge. If the results of an experiment are not published, knowledge is not gained. The final...

CASE Wyatt Earp - The Buffalo Hunter F. Robert Jacobs, Indiana University The legend of Wyatt Earp lives on largely based on his exploits as a gunfighter and Marshall of the frontier West in the 1880s. The classic tales of the shootout at the O.K. Corral in Tombstone or his sawed-off shotgun duel with Curly Bill are possibly the most celebrated gunfights of frontier history and cannot fail to stir the reader's imagination. Wyatt lived to be over 80 years...
