Normality: Is the number of gm equivalents of compound/ ions/ radicals per liter of solution. Note that the sum of normalities of +ve ions = that of –ve ions. Non-ionic dissolved species such as silica cannot be expressed in meq/L. Activity vs. concentration. TDS:

As a result, it takes twice as much base to neutralize it, making the concentration of the acid appear twice as large as it really is. 3) 0.1 M H2SO4 4) You cannot do a titration without knowing the molarity of at least one of the substances, because you’d then be solving one equation with two unknowns (the unknowns being M1 and M2).

Record the of acid volume consumed as B ml. OB Observation and Calculation: Wt. of Na2Co3 dissolved in 100ml distilled water = W gm. Therefore, The normality of Na2Co3 solution = W x 1000 / 53 x 100. S.No. Volume of Na2Co3 solution (ml) Vol. of H2SO4 used (Xml) 1-2-3-Volume of H2SO4 used in the standardization = X ml

1. Add 50 mL of water sample (Vs) to an erlenmeyer flask. 2. Add 4 to 5 drops of methyl orange indicator. 3. Read the starting volume of standard 0.02 N H2SO4 on the burette. Titrate water sample with standard 0.02 N H2SO4 until color changes from yellow-orange to red. 4. Read the final volume of the acid in the burette. Record volume used (Va). 5.

In order to determine the exact concentration of a sodium hydroxide solution you must standardize it by titrating with a solid acid that is not hygroscopic. Potassium hydrogen phthalate, KHC8H4O4 (abbreviated KHP), is a non-hygroscopic, crystalline, solid that behaves as a monoprotic acid. It is water soluble and available in high purity.

A titration is an analytical procedure used to determine the concentration of a sample by reacting it with a standard solution. One type of titration uses a neutralization reaction, in which an acid and a base react to produce a salt and water. In equation 1, the acid is HCl (called hydrochloric acid) and the base is NaOH (called sodium hydroxide).

3. Once the equivalence point has been calculated from the known concentration acid and the moles of Na2CO3, estimate graphically the pH at the first half equivalence point, the first equivalence point, and the second half equivalence point. 4. Calculate Kb1 from the initial pH and the pH at the first half equivalence point. Average these ...
