Diuretics
Drugs promoting urine output are known as diuretic drugs, which refer only to those agents that act directly on the kidneys. These drugs primarily increase the excretion of water and ions like sodium (Na+), chloride (Cl-, or bicarbonates HCO3-) from the body. Glomerular filtration, tubular reabsorption, and tubular secretion in kidneys determine the excretion of substances. They are employed in the treatment of various disorders like diabetes insipidus, nephrotic syndrome, hypertension,

Stage 3
Solution :
Given values
Concentration is given in percent so that take
mass of the solution = 100 g
mass of non-volatile solute = 2% = 2g
mass of the solvent = (100 — 2) = 98 g
molecular mass of solvent (water) = 18
We have to find molecular mass of solute
The vapour pressure of pure boiling water = 1atm = 1.013 bar.
Chemical Reactions: Concentration Effects & Enthalpy Changes
Aim: To study the effect of concentration on the rate of reaction between sodium thiosulphate and hydrochloric acid. Theory: Law of mass action states that rate of a chemical reaction is directly proportional to the product of active masses (molar concentrations) of reactants. The rate of reaction between sodium thiosulphate and hydrochloric acid depends on the concentration of reactants. As the concentration of reactants increases, the rate of reaction also increases. The balanced chemical reaction

Chemical Safety
Chemical reaction: a process in which atoms of one or more substances are rearranged to form different substances.
- Chemical reactions break food down into nutrients that the body can use.
- Chemical compounds are in our everyday life, from the plastics we use to the synthetic fibres that we wear and the healthcare products we put on ourselves.
- Chemicals used at school and in the workplace can be potentially harmful.
