titration of hcl using naoh. the concentration of standardized naoh is 0 . 1 0 0 1 mol l - 1 . note: all volume and ph measurements are accurate to 2 decimal places. if the displayed data shows less than 2 decimal places, a...
(Chemistry) an operation, used in volumetric analysis, in which a measured amount of one solution is added to a known quantity of another solution until the reaction between the two is complete. If the concentration of one solution is known, that of the other can be calculated ...
HCl → H+ + Cl- hydrochloric acid → hydrogen ion + chloride ion NH3 + H2 O ↔ NH4+ + OH- ammonia + water ↔ ammonium hydroxide Weak Base and Strong Acid Titration Curve The titration curve for a weak base - strong acid titration is different than that of a weak acid - strong...

1. Calculate the concentration of a 25 mL NaOH solution if 35 mL of 1.25 M HCl is needed to titrate to the equivalence point. NaOH + HCl → NaCl + H2O Answer: In this equation the mole ratio of NaOH (base) and HCl (acid) is 1:1 as determined by the balanced chemical equation...
potentiometric and photometric are used and the results obtained are compared. Total Alkalinity (m-value) of Water This application is used to determine the total alkalinity (m-value) of various water samples by titration with HCl. The endpoint of the titration is evaluated manually using the...
a) CH3COOH and NaOH b) HCl and NaOH c) CH3COOH and NH3 d) HCl and NH3 Answer : a) CH3COOH and NaOH A weak acid is titrated with a strong base, and the conjugate base of the weak acid will raise the pH to a value larger than 7 at the equivalence point.Unacademy...
