A solution on the shelf is not labeled for concentration but it is hydrochloric acid. If it’s pH is checked and found to be 0.4, what is its concentration?
Solution:-
Given : pH = 0.4
[H+] = 10-pH
[H+] = 10-(0.4) = 0.398 M
[HCl] = [H+] = 0.398 M

The Na,Co, solution described above was used to analyse a hydrochloric acid solution of unknown concentration. It was found that 24.30 mL of the Na,Co, solution was required to neutralise a 20.00 mL sample of the hydrochloric acid solution. 4. Using your answer to part 3 above, calculate the amount of Na,Co, present in 24.30 mL of the Na,Co, solution. (2 marks) 5. Using your answer to part 2 above, deduce the amount of HCl that was present in the...
It the K value for hydrochloric acid (HCI) is 1000, and the pH of the solution is 4 what is the concentration of HCI remaining in the solution at equilibrium? You will need to provide the chemical reaction, the charge balance, and mass balance. All info you need is provided here except the molecular weights. (6 pts)

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
A. Hydrochloric Acid Solution and pH 1. Write the balanced chemical reaction for the dissociation of the hydrochloric acid. 2. Refer to the procedure for A to determine the concentrations of the solutions of hydrochloric acid. Remember to use MiV1-MV. Show work for trial 1. 3. Calculate the theoretical pH of each hydrochloric acid solution. Recall that hydrochloric acid is a strong acid, suggesting complete dissociation, so that the equation pH log (HO) can be used (equation 3). Show work...
NORTHERN MICHIGAN UNIVERSITY CH112: Acid-Base Titration: Determining the Concentration of an Acid Solution Student Name: PRE-LAB (to be checked by the instructor before beginning the lab) 1. A 10.0 mL sample of hydrochloric acid is diluted by adding 50 mL of deionized water, and then titrated with a 0.1245 M solution of sodium hydroxide. If 26.75 mL of the sodium hydroxide solution are required to reach the equivalence point, what is the concentration of the original hydrochloric acid solution? 2....
1. What is the pH of a 0.0442 M solution of methylamine if enough hydrochloric acid is added to bring the chloride concentration to 0.0442? 2. What is the Ka value if a 0.0350M solution of an unknown weak acid yields a pH of 5.34?
17.04 ml of hydrochloric acid solution of unknown concentration is titrated with a 0.201 M standard solution of NaOH(aq). Compute the concentration of the hydrochloric acid solution given that 9.32 ml of the standard solution were added to reach the equivalence point.
Hydrochloric acid is sold as a concentrated aqueous solution. If the concentration of commercial is 12M and its density is 1.18g/cm3 , calculate the following: (a) the molality of the HCl solution (b) the weight percent of HCl in the solution. Please show the work on how to arrive at these answers - a. 16.2m b. 37.1%
