∙ 11y agoWhen excess zinc metal is used in a reaction, it can be removed by simple filtration, as long as the particles are big enough. If the zinc particles are too small to be removed by filtration, other techniques such as centrifugation must be employed.

When there is excess water in your body fluids, your kidneys will produce more dilute urine to help get rid of the excess water. This results in a higher volume of urine that is more clear and less concentrated.
Excess urea in the body is primarily removed by the kidneys through urine excretion. Increasing fluid intake can help dilute urea levels and promote its excretion. In severe cases, dialysis may be necessary to remove excess urea from the blood.
Uranium hexafluoride is made from uranium dioxide or uranium tetrafluoride by adding fluorine gas. The process involves reacting uranium compound with an excess of fluorine gas under controlled conditions to produce uranium hexafluoride.
Excess ice is removed from water before adding salt because the ice will dilute the salt and interfere with the process of creating a concentrated brine solution. Removing excess ice ensures that the proper salt-to-water ratio is maintained for the desired outcome, such as when making a brine for pickling or preserving food.
Aniline can be converted into phenyl hydrazine by reacting it with hydrazine hydrate in the presence of an acid catalyst such as hydrochloric acid. The reaction proceeds through the formation of a diazonium salt intermediate, which then reacts with excess hydrazine to form phenyl hydrazine.
When copper oxide is added into excess dilute sulphuric acid, it reacts to form copper sulfate and water. Additionally, hydrogen gas is evolved during the reaction.
When excess copper oxide is added to dilute sulfuric acid, the excess copper oxide will react with the acid to form copper sulfate and water. The reaction will continue until all the copper oxide is used up. This is known as a limiting reactant situation, where one reactant is completely consumed before the other.
Dilute hydrochloric acid? Carbon dioxide gas escapes and leaves sodium chloride solution, possibly leaving either an excess of acid, or an excess of sodium carbonate.
Excess magnesium in sulfuric acid can be removed by adding a dilute acid, such as hydrochloric acid, to convert the magnesium to soluble magnesium chloride, which can be filtered out. Alternatively, the solution can be allowed to stand so that any unreacted magnesium settles to the bottom, and the supernatant can be decanted.
Drinking excess water sometimes causes hyponatremia, because the absorption of water into the bloodstream can dilute the sodium in the blood.
to ensure that all the sulphuric acid has been used up
The precipitate of salicylic acid dissolves in excess sulphuric acid due to the formation of a complex between salicylic acid and sulphuric acid, which increases the solubility of the precipitate. This reaction results in the formation of a colorless solution, as the salicylic acid is converted into its conjugate base form.
Zinc hydroxide dissolves in excess dilute sodium hydroxide because it forms a complex ion, [Zn(OH)4]^2-, which is soluble in aqueous solution. This complex ion helps stabilize the zinc hydroxide and prevents it from precipitating out of solution.
Your body takes on excess water and gets rid of what it doesn't need. If excess water was allowed to accumulate in the blood, you would have dilute, watery blood, which would not do its job properly.
Sulfur dioxide can be prepared in the laboratory by reacting sulfur with oxygen or air. This reaction is typically carried out in a combustion chamber where sulfur burns in the presence of excess oxygen to form sulfur dioxide gas. The gas can then be collected using a suitable apparatus.
In a direct titration, a known concentration of a titrant is added to a solution to determine the concentration of an analyte directly. In back titration, a known excess of titrant is added to the analyte, reaction occurs, and the remaining excess is titrated with another reagent to determine the concentration of the analyte.
CaCO3 + HCl --> CaHCO3 or with excess of HCl CaCO3 + 2HCl --> CaCl2 +CO2 + H2O
