Sulfuric acid is a strong acid and dissociates in water as shown in Equation 5.

H2SO4 (aq) = 2H+ (aq) + SO42− (aq)     (Equation 5)

What is the hydrogen ion concentration, in mol dm−3 when 2.00 g of sulfuric acid is dissolved in water to give 0.400 dm3 of solution? (Show all of your working and give your answer to three significant figures.)

What is the corresponding pH of the solution in part (b)(i)? (Show all of your working and give your answer to two significant figures.)

± The Nernst Equation and pH Sulfuric acid is a very strong acid that can act as an oxidizing agent at high concentrations (very low pH, or even negative pH values). Under standard conditions, sulfuric acid has a low reduction potential, SO42−(aq)+4H+(aq)+2e−⇌SO2(g)+2H2O(l),   +0.20 V which means it cannot oxidize any of the halides F2, Cl2, Br2, or I2. If the H+ ion concentration is increased, however, the driving force for the sulfuric acid reduction is also increased according to Le Châtelier's...

What was the molarity of the KOH solution if 11.7 mL of 1.50 M H2SO4 was needed? The equation is 2KOH(aq)+H2SO4(aq)→K2SO4(aq)+2H2O(l) Express your answer with the appropriate units. Hints Part B Redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. For example, a solution of hydrogen peroxide, H2O2, can be titrated against a solution...

Based off info below please answer blank boxes. Thanks! Application Questions: 12. Before using a solution of NaOH as a standard for a titration, its precise concentration must be determined by titration with a standard acid. This is because solid NaOH absorbs water from the atmosphere, so its solid form is difficult to keep free of contaminated H2O. A common acid used for standardization is the acid-salt, potassium hydrogen phthalate (KHP), KHC8H4O4. Another way is to use a standardized solution...
