Cause and Effect Example
CORROSION In general, corrosion is the destruction of metal objects due to environmental influences. The corrosion process can be explained electrochemically, for example in the process of ironing which forms iron oxide (F2O3.nH2O). Electrochemically, the process of ironing is an iron oxidation event of iron by oxygen from the air. Corrosion can also be interpreted as an attack that damages the metal because the metal reacts chemically or electrochemically with the environment. There is another definition which says that corrosion is the opposite of a metal extraction process from its mineral ore. For example, iron ore minerals in the wild are present in the form of iron oxide or iron sulphide compounds, after extracting and treating, an iron will be produced for the manufacture of steel or alloy steel. During use, the steel will react with the environment causing corrosion (back to the iron oxide compound). For iron metal is left open in the yard for a mo...
Hi zelvy, please explain about definition of the colligative proporties solution? thanks
BalasHapusColligative properties are properties of solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the nature of the chemical species presen
HapusCan you give example for osmotic ? Thanks
BalasHapusAn example of the osmotic pressure in everyday life is the entry of ground water into the crop through the root cell. An osmosis event will create an osmotic pressure
HapusExplain the nature of the colligative and give an example
BalasHapusThe colligative nature of the solution is the properties that depend only on the quantity of solute particles in the solution and does not depend on the type or identity of the solute particles - no matter in the form of atoms, ions, or molecules.
HapusFor example
Steam Pressure Decrease
Boiling Point Increase
Decrease of Freezing Point
Osmosis Pressure
Can you explain colligative with understanding, example you can show not just theorical, but practical?
BalasHapuszelvy, What do you know about osmotics?
BalasHapusThe osmotic pressure is the hydrostatic pressure that forms in the solution to stop the solvent osmotic process into the solution through a semi-permeable membrane.
HapusAs mentioned, the amount of external pressure (osmotic pressure) is equal to the pressure to perform the osmosis.
