Chlorinity in Water using Mohr-Knudsen Method

Description

Chlorinity is a measure of the total concentration of halides (mainly chloride) in seawater.

Principle:

Titration of chloride ions in seawater with silver nitrate, forming a precipitate of silver chloride. Potassium chromate is used as an indicator, which turns red when all chloride has reacted and silver chromate begins to form. The volume of silver nitrate used corresponds to the chlorinity of the sample. Chlorinity is then converted to salinity using a standard formula. APHA(2017,ISBN:9780875532875).

Usage

CL(chl_std_seawater, T1, T2)

Arguments

chl_std_seawater	Chlorinity of standard seawater
T1	Volume of silver nitrate required to titrate a sample
T2	Volume of silver nitrate required to titrate standard seawater

Value

Chlorinity in Water(gm/L)
