d. (5 Points) A 150 mL portion of 0.250 M HCl solution was titrated with NaOH; It took 100. mL of a 0.375 M base to neutralize the sample. If only 70.0 mL of NaOH were added to the 150.0 mL portion of HCl, what is the molarity of the HCl remaining in solution?
A 50.00-ml NaOH sample of unknown concentration was titrated with 0.1274 M HCI.
Titrations 1. A 50.00-ml NaOH sample of unknown concentration was titrated with 0.1274 M HCI. if 33.61 mL of the HCl solution were required to neutralize the NaOH sample, what is the molarity of the NaOH sample? Show the steps in your calculation 2. A 25.00-ml HCl sample of unknown concentration was titrated with 0.5631 M Al(OH)3. If 37.62 mL of the Al(OH) solution were required to neutralize the HCl sample, what is the molarity of the HCl sample? (Assume Al(OH)3 is...

1. A student prepared a base solution using 7 mL of 6M NaOH diluted with distilled water to a final volume of approximately 400 ml. The student titrated a standardized solution of HCI to determine the exact concentration of the prepared base solution. In the first titration she found that it took 22.47 mL of the base solution to neutralize 20.00 mL of a 0.98861 M HCl solution. In the second titration, she found that it took 20.12 mL of...
