What happens when electric current is pass through a colloidal solution?
When an electric current is passed through a colloidal solution, the colloidal particles may migrate towards the electrodes due to the electrical charge. This process is known as electrophoresis. Additionally, the movement of colloidal particles may cause them to coagulate or form larger aggregates.
What happens if a colloid is passed through a filter?
When a colloid is passed through a filter, the larger particles of the colloidal suspension do not pass through the filter membrane, while the smaller solvent molecules can. This results in the separation of the colloidal particles from the dispersing medium. The filter retains the colloidal particles, leading to a clearer solution on the other side, which contains primarily the solvent and any small dissolved substances. Therefore, filtration effectively removes the colloidal particles from the mixture.
What happens when electric current passed through the colloidal sols?
The cations and anoin moves towards opposite electrodes ... or they will settle at the bottom
What happens when an electric current is passed through a solution?
Either the bulb will start glowing or the magnetic needle will show deflection
When electric currents is passed through a conducting solution what happens?
Either the bulb will start glowing or the magnetic needle will show deflection
What happens when dry HCl gas is passed through saturated solution of sodium?
When dry HCl gas is passed through a saturated solution of sodium chloride (NaCl), no visible reaction occurs. The sodium chloride remains dissolved in the water, as HCl gas does not react with NaCl in this situation.
What happens when carbon dioxide is passed through NaOH solution?
2 NaOH(aq) + CO2(g) = Na2CO3(aq) + H2O(l)
What gas that passed through into an acidic dichromate solution and turn the solution from orange to green?
Sulfur dioxide gas passed through an acidic dichromate solution turns the solution from orange to green.
Is sea water passed through a sieve solution?
Sea water is a solution.
What happens when sulphuric acid is passed through charcoal?
When sulfuric acid is passed through charcoal, the charcoal adsorbs the acid molecules on its surface due to its porous nature. This absorption process helps to remove sulfuric acid impurities from the solution. The charcoal acts as a filter, trapping the acid molecules and purifying the solution.
What happens when a solution is ionic does the light bulb glow?
When a solution is ionic, it contains charged particles (ions) that can conduct electricity. If an electric current is passed through the solution, the ions move and allow the flow of electricity. If a light bulb is connected in the circuit and the ionic solution is conductive enough, the bulb will glow, indicating that the current is flowing through the solution.
What happen When a strong beam of light is passed through a colloidal solution?
If the colloid is metallic (e.g. silver or gold), then the current will increase, as the colloid is more conductive than plain water. The current will strip off atoms of a donor metal (silver or gold) which will want to migrate to the opposite polarity (pos and neg), if the voltage and current are correctly set, the particle size will be small and will stay in solution and become a colloidal solution. Tiny amounts of current is key here. In the few milliamp range. 27v - 30v DC and 5 - 20 ma is best for making a colloidal silver for example, as at such low amps, the particle size is very small, and is a true colloid.
