A 50.0 mL sample of aqueous sodium hydroxide is titrated with 0.425 M sulfuric acid, and 57 mL are required to reach the equivalence point. Write the balanced chemical equation for this reaction. Answer: A 50.0 mL sample of aqueous sodium hydroxide is titrated with 0.425 M sulfuric acid, and 57 mL are required to reach the equivalence point. What is the molarity of the initial sodium hydroxide solution? Hint: You will need the balanced chemical equation you provided as your answer to the previous question. Report your answer to the correct number of significant figures and with the correct units. Answer:

Some soluble compounds are listed in the table below. Complete the table by filling in the name or chemical formula of each compound, whichever is missing. (If there is more than one way to name the compound, choose the name used when the compound is dissolved in water.) Also classify the compound using the checkboxes. compound HCH, CO₂ 0 0 NH₂ name 0 sodium perchlorate hydrobromic acid 0 type of compound (check all that apply) strong weak strong weak acid acid base base ionic molecular O O O O O O X 5

A 15.5 mL sample of 0.800 M NaOH was titrated with an acid. It required 25.0 mL of the acid to reach the equivalence point. The molarity of the acid is

The titration on the right was performed by placing 10.00 mL solution in an Erlenmeyer flask and titrating it with 0.1000 M HCl.  How would you classify the species being titrated in this titration? diprotic weak base monoprotic weak base triprotic weak acid triprotic weak base diprotic weak acid monoprotic weak acid

A student is given the following labeled solutions: NaCl, AgNO3, FeCl2, HCI, and KaCo The data was collected and summarized in the following table. The student then receives 5 test tubes labeled A, B, C, D, and E, which contain the five solution above. Data collect after mixing these solutions are given in the second table below. 4.

The answer is not 4.8 x 10^-10 please find the correct answer. Thank you!

A sample of oxalic acid (a diprotic acid of the formula H2C2O4) is dissolved in enough water to make 1.00 L of solution. A 100.0 mL sample of this solution is titrated with a solution of sodium hydroxide (NaOH) of concentration 0.750 M and requires 20.0 mL of sodium hydroxide to reach the end point. Calculate the mass of the original oxalic acid sample. H2C2O4 + 2NaOH → Na2(C2O4)+ 2H2O

25.0-mL samples "A" and "B" (both containing HCl) were titrated with 0.100 M NaOH.  When titrating sample "A", it took 23.8 mL of titrant to reach the endpoint.  When titrating sample "B", it also took 23.8 mL of titrant to reach the endpoint.  Which of the following is correct?   a. Sample A has a higher concentration of HCl b. Sample B has a higher concentration of HCl c. Sample A has the same concentration as Sample B d. We are unable to deduce the concentration of either sample.
