Hydroxide ions Homework • Unanswered Estimate the molar concentration of hydroxide ions OH in vinegar. Enter your answer using this type of scientific notation: X.XEY Numeric Answer: The concentration of acetic acid (CH3COOH) in common vinegar is close to 1M. Not all the molecules of this acid react with water molecules and produce H3O+ ions. In fact, only around 4 per every 1000 molecules of acetic acid...

For the following dissociation of acetic acid, Ka = 1.760 x 10-5: CH3COOH + H2O ? CH3COO- + H3O+ Sodium acetate completely dissociates in solution according to the following reaction: NaCH3COO ? Na+ + CH3COO- A solution was prepared which contains CH3COOH at a pre-equilibrium concentration of 0.05782 M and NaCH3COO at a pre-equilibrium concentration of 0.04991 M. I know all answers, just do not know how to find them. What is the equilibrium concentration of H3O+? (Answer: 0.00002037) What...

Answer A & D are
incorrect
Vinegar, whose main ingredient is acetic acid(CH2COOH) is often mixed with baking soda (NaHCO3) to unclog drains that reacts in the following manner: CH3COOH(aq)+ HCO3 (aq)--CH3C00"(aq)+H2CO3(aq) (Needed information for questions 3-5) Acetic acid (CH2COOH), which has a pKq=4.74) Question 3 Homework. Unanswered If the pkb for HCO3 is 10.4, what is true of this reaction? A product-favored because the reactants are weaker O B reactant-favored because the products are weaker 0 C reactant-favored because...

6. Vinegar is 5.00% (m/v) acetic acid (CH3COOH). How many milliliters of vinegar would you need to react with an excess of baking soda (NaHCO3) in order to generate 10.0 L of carbon dioxide gas at 1.05 atm and a temperature of 25.0°C? 7. Shown below is the aqueous reaction of KNOX, HCl, and SnCl2. 2 KNO2 (aq) + 6 HCl(aq) + 2 SnCl2 (aq) → 2 SnCla (aq) + N20 (g) + 3 H20 (1) + 2 KCl (aq)...

Acid-Base Chemistry: Unknown Acid Analysis (in two experiments) Introduction In this experiment you will titrate a monoprotic weak acid with a strong ak acid with a strong base in the nd using a pH meter (Exp 2). An analysis of concentration and molar mass of the the titration data will allow you to determine the concentration and more unknown acid (Exp 1) and the ionization constant Ka (Exp 2). At the...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
