QUESTION 1 After titrating a 58 ml solution of NaOH using 32 mL of 2 M...
25.00 mL of a sulfuric acid solution was standardized by titration with 0.2500 M NaOH using phenolpthalein indicator. 30.52 ml of the NaOH was required. Find the molarity of the sulfuric acid. H2SO4 (aq) + 2NaOH (aq) ----> Na2SO4 (aq) + 2H2O (l)
A solution of 0.154 M NaOH is used to neutralize 25.5 mL of a H2SO4 solution. If 25.0 mL of the NaOH solution is required to reach the endpoint, what is the molarity of the H2SO4 solution? H2SO4(aq)+2NaOH(aq)→2H2O(l)+Na2SO4(aq)
Suppose you are titrating a sulfuric acid solution of unknown concentration with a sodium hydroxide solution according to the equation H2SO4 + 2NaOH + 2H2O + Na2SO4 If you require 28.52 mL of 0.904 M NaOH solution to titrate 209.1 mL of H2SO4 solution, what is the concentration of the H2SO4 solution? Type answer:
Consider the reaction H2SO4(aq) + 2NaOH(aq) → 2H2O(l) +Na2SO4(aq). If 25 mL of H2SO4 was needed to react with 15 mL of 0.20 M NaOH, what is the molarity of the H2SO4(aq)?
1) A flask containing 450.0 mL of 0.500 M HBr was spilled on
the floor. How many grams of K2CO3 would you need to put on the
spill to neutralize the acid according to the following
reaction?
2 HBr (aq) + K2CO3 (s) => 2KBr (aq) + H2O (l)
2) Determine the molarity of an unknown NaOH solution if 25.00
mL of sodium hydroxide was titrated with 15.00 mL of a 1.500 M
sulfiric acid solution (H2SO4). (aOH= 40.00 g/mol...
if 38.2 mL of a 0.163 M KOH solution is required to titrate 25.0 mL of a solution of H2SO4, what is the molarity of the H2SO4 solution. H2SO4 (aq) + 2 NaOH (aq) -----> 2H2O (l) + Na2SO4 (aq)
Question 6 (1 point) In titrating 0.20 M sulfuric acid, H2SO4, with 0.40 M NaOH at 25°C, the solution at the equivalence point is 00.20 M Na2SO4 Overy acidic O slightly acidic O 0.10 M H2SO4 and 0.40 M NaOH O 0.10 M Na2SO4
Sulfuric acid (250.0mL) is titrated with 176.5 mL 2.4 M NaOH to an equivalence point (the point where all the sulfuric acid is exactly neutralized). 2NaOH + H2SO4 -> 2H2O + Na2SO4 a) How many moles of Sulfuric acid were in the original 250.0 mL? moles of H2SO4 = b) What was the concentration of Sulfuric acid in the original 250.0 mL sample? Molarity of Sulfuric acid =
Calculate the molarity of H2SO4 that results after 10.0 mL of H2O are added to 25.0 mL of 0.500 M H2SO4 in preparation for the following reaction. Assume the volumes are additive. H2SO4(aq)+ 2NaOH—> Na2SO4(aq) + 2H2O(l) answer is: 0.357 M
How many milliliters of 0.100 M NaOH are required to neutralize 65.0 mL of 0.250 M H2SO4 ? The balanced neutralization reaction is: H2SO4(aq)+2NaOH(aq)→Na2SO4(aq)+2H2O(l).
