We are asked to explain the pH and how to find hydrogen ion concentration.
Find the pH of an acidic substance of your choice. Using this pH, show how to find the hydrogen ion concentration, [H+], of the substance using the formula. Discuss the meaning of pH and [H+], the pH scale and why your chosen substance is acidic. Use scientific notation or enough decimal places so that your answer has at least 3 place values. For example, either use 3.44*10-6 or 0.00000344.
Identify the weaker acid in each of the following pairs: a)HNO3 or HCO3^- b)HSO4^- or H2O c)H2SO4 or H2CO3
Given the reaction: 2Al + 3H2SO4 -> 3H2 + Al2(SO4)3 what would be the total number of moles of H2SO4 needed to react completely with 5.0 moles of Al ?
The white solid that remains in the centrifuge tube after acetone extraction fizzes when hydrochloric acid is added, suggesting that sodium carbonate is present. How did this substance form? Give a balanced equation for its formation.
What is the molarity of a permanganate solution if it takes 10.0 mL of 0.200M iron(II) solution to completely react with 15.7 mL of the permanganate solution
Draw one eclipsed and one staggered conformation of 2,3-dimethylpentane using: Newman projections that sights down the C2-C3 bond, Sawhorse projections that sights down
You titrate 1.740 g of a solid unknown acid that was dissolved in 100.0 mL of distilled water; the initial pH value was 2.5. You found that pH= pKa=4.2 when 12.50 mL of NaOH was added. The concentration of the sodium hydroxide was 0.500M. Calculat..
Classify the following compounds and ions as strong acid, weak acid, strong base, weak base, or neutral. For each write the reaction(s) that justify your decision. If a substance is amphiprotic, show both reactions.
What is the final concentration of Na+ after adding 230 ml of water to a stock solution of 2.5M 420.0 ml Trisodium phosphate?
An automobile has a wavelength that is not measurable by human standards. If the car has a mass of 4000 lbs (1.81 x 103 kg) and travels at 60 miles/hr (26.8 m/s), calculate the wavelength of the car.
Rb has two naturally occurring isotopes 85Rb and 87Rb, with masses 84.9118 amu and 86.9092 amu, respectively. The average atomic mass is 85.468 amu.
A 0.01 M solution of hyperchlorous acid , which is a monoprotic acid, has a pH of 6.5 at 67 degrees C. Determine the Ka value of this acid.
