In a hiring freeze, an employer decides to stop hiring employees for all non-essential positions. It allows an employer to consolidate current employees and potentially restructure departments to complete the work that is essential for serving the customers of the business.
Since the electrical conductivity is a measure to the capacity of water to conduct electrical current, it is directly related to the concentration of salts dissolved in water, and therefore to the Total Dissolved Solids (TDS). Salts dissolve into positively charged ions and negatively charged ions, which conduct electricity.
Conductivity is the ability of water to conduct an. electrical current, and the dissolved ions are the conductors. The major positively. charged ions are sodium, (Na+) calcium (Ca+2), potassium (K+) and magnesium (Mg+2). The major negatively charged ions are chloride (Cl-), sulfate (SO. 4. -2), carbonate (CO.
