How can you separate sulfur from water?
Sulfur is insoluble in water so it can be removed by filtration.
What is potassium hydroxide or sodium hydroxide?
What do you want to know about it? Potassium hydroxide will dissolve in water to form a solution containing disassociated Ka+ and OH- ions. Potassium hydroxide is a strong alkali. Potassium hydroxide has the chemical formula KOH.
What substance can be used to get rid of sulphur dioxide?
Sulfur doxide can be removed with a caustic solution such as NaOH in water.
Does a metallic element form an acid or base when it reacts with water?
Usually a metallic element will not react with water and so will not change pH. However, a highly reactive metal, such as sodium, potassium or calcium will react with water to form the corresponding metal hydroxide, and so forms a base.
How do you fix toxic soils?
depends on what is the cause of toxidity. some can be washed away, others can be removed by growing the right plants on them and others you simply have to wait for them to decompose or a new solution found
How are the insoluble solids removed from the water?
For insoluble impurities a method is ultrafiltration.
How insoluble particles can be removed from hot solution?
Insoluble particles can be removed from hot solution by filtration.
How are insoluble impurities removed during recrystallization?
Using a gravity filtration. The desired compound that is dissolved in the heated solvent will pass through the filter and any insoluble impurities will be caught in the filter.
How does the recrystallization produce remove solvent soluble impurities?
Soluble impurities are removed by a process of vacuum filtration
How are soluble impurities removed during a recrystallization?
Soluble impurities are removed during recrystallization by dissolving the impure solid in a hot solvent, then filtering the hot solution to remove insoluble impurities. The solution is then cooled slowly, allowing the pure compound to crystallize out while the impurities remain in solution. The pure crystals can be separated from the solution by filtration.
How would you describe the process of sedimentation.?
Sedimentation is a process in which insoluble particles can be removed from water or any other liquid item.when the impurities in the liquid is stirred and left for a while the impurities in the liquid will gradually settle down at the bottom of the container.This is a process of the settling down of the suspended impurities.
How can insoluble particles can be removed from a hot solution?
Insoluble particles in a hot solution can be removed by allowing the solution to cool down, causing the particles to settle at the bottom. The clear liquid can then be carefully decanted or filtered to separate it from the insoluble particles. Alternatively, a centrifuge can be used to separate the solid particles from the liquid.
What is the substance which reacts with unwanted impurities in ores to form a fusible mass which can easily be removed?
The substance that reacts with unwanted impurities in ores to form a fusible mass is called a flux. Fluxes are added during the smelting process to help separate the impurities from the desired metal, forming a slag that can be easily removed.
Which solvent can be removed from insoluble solute?
sand and water
What remain after the impurities have removed from water?
Ultrapure water is obtained.
Why are the group 1 cations removed as insoluble chlorides?
Group 1 cations (Li+, Na+, K+) are removed as insoluble chlorides (LiCl, NaCl, KCl) because they form stable and insoluble precipitates with chloride ions in acidic solutions. This precipitation process allows for the separation of group 1 cations from other cations present in the solution.
Assuming that charcoal and sugar are the main impurities present in a sample of crude acetanilide explain how recrystallization from water would remove each..?
Recrystallization from water would remove charcoal impurities by dissolving the acetanilide in hot water, as charcoal is insoluble in water. The sugar impurities would also be removed because they are more soluble in hot water than in cold water, so they would remain dissolved during the recrystallization process and be removed in the mother liquor.
