What are the methods of determination of chlorides?

What are the methods of determination of chlorides?

The concentration of chloride ions is determined by subtracting the titration findings of the moles of silver ions that reacted with the thiocyanate from the total moles of silver nitrate added to the solution. This method is used when the pH of the solution, after the sample has been prepared, is acidic.

What process is used to remove excess chloride in water?

reverse osmosis system
The good news is that chlorides can easily be removed from water with either a reverse osmosis system or a distiller. Reverse osmosis works by passing water through a semi-permeable membrane that separates pure water into one stream and salt water into another stream.

What is the chloride effect?

The chloride shift or “Hamburger effect” describes the movement of chloride into RBCs which occurs when the buffer effects of deoxygenated haemoglobin increase the intracellular bicarbonate concentration, and the bicarbonate is exported from the RBC in exchange for chloride.

What is the significance of determination of chloride content in water?

The measured chloride ions can be used to know salinity of different water sources. For brackish water (or sea water or industrial brine solution), it is an important parameter and indicates the extent of desalting of apparatus required.

What is the indicator in the Mohr method of chloride determination?

The Mohr method uses chromate ions (CrO42-) as the indicator for the argentometric determination of bromide, chloride and cyanide ions.

Which titration method can be used for quantitative determination of nacl?

Chloride is determined by potentiometric titration with a standard silver nitrate solution using an automatic titrator.

Does RO remove chlorides?

Reverse Osmosis will remove 90 – 95\% of the chlorides because of its salt rejection capabilities. Electrodialysis and distillation are two more processes that can be used to reduce the chloride content of water.

What is the effect of chloride in water?

Chloride increases the electrical conductivity of water and thus increases its corrosivity. In metal pipes, chloride reacts with metal ions to form soluble salts (8), thus increasing levels of metals in drinking-water. In lead pipes, a protective oxide layer is built up, but chloride enhances galvanic corrosion (14).

What is meant by chlorides?

Definition of chloride 1 : a compound of chlorine with another element or group especially : a salt or ester of hydrochloric acid. 2 : a monovalent anion consisting of one atom of chlorine.

What is chloride shift mechanism?

Chloride shift (also known as the Hamburger phenomenon or lineas phenomenon, named after Hartog Jakob Hamburger) is a process which occurs in a cardiovascular system and refers to the exchange of bicarbonate (HCO3−) and chloride (Cl−) across the membrane of red blood cells (RBCs).

What is the disadvantage of the Mohr method?

A) (ii) Disadvantages of Mohr Method  Mohr’s method is suitable only for titration of chloride, bromide and cyanide alone.  Errors can be introduced due to the need of excess titrant before the endpoint colour is visible.  Before to the end-point of the titration, chloride ions remain in excess.

What is the effect of chloride on water?

Chloride increases the electrical conductivity of water and thus increases its corrosivity. In metal pipes, chloride reacts with metal ions to form soluble salts (8), thus increasing levels of metals in drinking-water. In lead pipes, a protective oxide layer is built up, but chloride enhances galvanic corrosion (14).

What is the recommended limit of chloride in water?

The recommended limit of chloride in water is <250 mg/L. View chapter Purchase book

What are the corrosive effects of chlorides on metals?

Corrosive Effects of Chlorides on Metals 145 salt will attack and destroy the passive film more quickly than it can be repaired in a low oxygen environment. Some metals show preferential sites of pit nucleation with metallurgical microstructural and microcompositional features defining the susceptibility.

What is the significance of the chloride concentration measurement of serum?

Chloride concentration measurement of serum (Table 1) is meaningful in the case of normal water concentration of the sample. In hyperlipemia or hyperproteinemia, ‘grouped’ occurs, because an increase of, e.g., 10\% in the macromolecule-containing compartment decreases chloride concentration by 10\%.
