need help solving You have 45.0 mL of sample of nitric acid at an unknown concentration....
you are asked to tittate a sample of sulfuric acid of unknown concentration against a standardized solution if sodium hydroxide. you stsrt with 23.00 mL of sulfuric acid in a reaction flask, and 25.67 mL of 1.760 M sodium hydroxide are required to reach the equivalent point, what is the molarity (M) of the sulfuric acid solution? please show conversion steps!
50.00 mL of unknown calcium hydroxide solution is titrated with 0.300 M standard nitric acid solution. If 42.21 mL of the standard acid so lution is required to reach a phenolphthalein endpoint, what is the molarity of the unknown calcium hydroxide solution? (Hint: write the balanced formula unit equation.)
The total acid concentration (nitric + nitrous acid) of the 10.0 mL solution of “acid rain” is determined by an acid-base titration method. You add 5.00 mL of the titrant sodium hydroxide with a concentration of 0.0114 M to reach the endpoint. .Write one net ionic equation for the acid-base reaction occurring during titration (Think in context of what chemical species in solution are reacting with each other to get a color change at endpoint) .
10.00 mL Nitric acid was titrated with NaOH of 0.100 molarity until the equivalence was reached. 15.2 mL of NaOH were required. Find: A) Concentration of nitric acid before titration B) pH of solution before titration C) pH of solution after 15.1 mL of sodium hydroxide is added D) pH of solution after 15.3 mL of sodium hydroxide is added
You need to neutralize a solution of an unknown concentration of sodium hydroxide before you can dispose of it. In the lab, you have a 5.0M bottle of hydrochloric acid, however, you want to dilute that first to use a less concentrated (and less dangerous) solution. So, you decide to use a 0.1M solution of hydrochloric acid solution and to make 2.0 litres of it. (a) Show all calculations for how you would do this. (b) Once you have your...
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:
A 25.00 mL sample of nitric acid requires 19.63 mL of 0.1103 M NaOH to reach the end point of the titration. What is the molarity of the nitric acid solution? 0.536 grams of KHP were added to 100.0mL of water. What is the molarity of the KHP solution? (Do not type units with your answer.) Following the procedure for today's lab, a 0.0206 M KHP solution requires 24.59 mL of NaOH solution to titrate it. What is the molarity...
To determine the concentration of a solution of hydrochloric acid, a 75.00-mL sample is placed in a flask and titrated with a 0.1312 M solution of sodium hydroxide. A volume of 43.33 mL is required to reach the phenolphthalein endpoint. Calculate the concentration of hydrochloric acid in the original sample
If 25 mL of nitric acid is titrated with 0.12 M sodium hydroxide and it took 10 mL of the sodium hydroxide to fully neutralize the nitric acid, what was the concentration of the nitric acid at the start of the titration? D View hint for Question 19 Question 20 (4 points) How many milliliters of 2.25 M HCl would be required to titrate 6.00 g of KOH? Your Answer: Answer units
A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1435 M standard sodium hydroxide solution. He takes a 25.00 mL sample of the original acid solution and dilutes it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 13.55 mL of the standard solution. What...
