The number of moles of
Concept introduction:
Moles of the chloride ion are equal to the moles of the silver ion added in the system in the titration of the chloride ion sample with silver nitrate. Numbers of moles are defined as the given mass of the species divided by the molar mass of that species.
(b)
Interpretation:
The concentration of the chloride ion in the diluted solution is to be determined.
Concept introduction:
The concentration of the chloride ion present in the unknown sample is determined by the argentometric titration. The chloride ion sample is titrated with the silver nitrate solution to calculate the concentration of the chloride ion.

- 10.0 mL of 0.100 M HCl solution was added to 20.0 mL of 0.100 M (CH3CH2)3N (triethylamine). Kb (CH3CH2)3N = 5.2 x 10–4 Determine the following: a) Concentration of (CH3CH2)3N that did not react with acid. b) Concentration of (CH3CH2)3NH+ formed from the reaction with acid. c) pOH.arrow_forward100 mL water sample was subjected to DO analysis using the Winkler method. The initial reading of the titrant (0.025 M Na2SO3) in the buret was 2.51 mL. The endpoint was obtained and the final reading was 7.07 mL. A blank was also titrated and 0.75 mL of the titrant was consumed. Compute for the amount of DO (mg/L) in the sample.arrow_forwardAmy is testing the concentration of muriatic acid (hydrochloric acid) to check that the concentration is within certain limits. She titrated a 15.0 mL sample (diluted by a factor of 10) with a standard sodium hydroxide solution. A volume of 10.00 mL of 0.125 mol/L sodium hydroxide is used to neutralize the acid. a.

- Prepare another 5 cuvettes with different concentration of Pi using the stock 1mM Pi, 0.5mM PNPP solution (in water) and 0.2M Tris-HCl, pH=8.00. For this part, the concentration of PNPP will remain constant at 0.150mM. Fill the table below (before coming to lab) and use it to prepare your cuvettes. The completed table must be in your pre-lab. Your blank for each reaction is the PNPP mixed with Tris-HCL and Pi. Again, prepare one cuvette at the time to minimize exposure of the PNPP to the air. You can prepare your next cuvette while your previous one is being read. previous one is being read.
