What else can I help you with?
Why is excess amount of sodium hydroxide added to the conical flask?
Excess sodium hydroxide is added to ensure that all the acid in the solution is fully neutralized. This helps to guarantee that the reaction goes to completion and that the pH of the solution is sufficiently raised.
How will you change the aspirin to make it water soluble?
Usually by converting it to its sodium salt, by reaction with sodium hydroxide.
What is the balanced equation for zinc hydroxide react with excess sodium hydroxide?
There is no reaction between zinc hydroxide and sodium hydroxide.
What is the predicted effect on the reaction of zinc nitrate and excess sodium hydroxide?
The reaction of zinc nitrate and excess sodium hydroxide begins with precipitation of zinc hydroxide ( Zn(OH)2 ), followed by dissolvement after adding excess sodium hydroxide ( 2 OH- ) to formation of zinc aat-ions ( [Zn(OH)4]2- )
How is the concentration of hydroxyl ions affected when excess base is dissolved in a solution sodium hydroxide?
The concentration of hydroxyl ions will increase because sodium hydroxide dissociates in water to release hydroxide ions. The excess base will increase the amount of hydroxide ions present in the solution, leading to a higher concentration of OH- ions.
Why is sodium hydroxide added into the conical flask containing a analgesic or aspirin?
to decrease ph
When sodium hydroxide dissolve in water estimate the temperature change when the amount sodium hydroxide is doubled?
When sodium hydroxide dissolves in water, it undergoes an exothermic reaction, releasing heat. If the amount of sodium hydroxide is doubled, the same amount of heat will be released, resulting in an increase in temperature. The specific temperature change would depend on the initial amounts and concentrations of the sodium hydroxide and water.
What is formed when Excess of sodium hydroxide react with zinc?
This reaction is to be carried out with Sodium hydroxide dissolved in water and Zinc oxide. The product is Sodium Tetrahydroxidozincate(2-) or Simply Sodium Zincate.ZnO + 2 NaOH + H2O ----> Na2Zn(OH)4
How many grams of sodium hydroxide will react with 150g of phosphoric acid sodium phosphate is one product?
To find the amount of sodium hydroxide needed to react with 150g of phosphoric acid, you first need to determine the balanced chemical equation between sodium hydroxide and phosphoric acid. From there, you can use stoichiometry to calculate the amount of sodium hydroxide needed.
How do you find solubility of carbon dioxide in sodium hydroxide?
To find the solubility of carbon dioxide in sodium hydroxide, you can conduct an experiment where you bubble carbon dioxide gas through a solution of sodium hydroxide and measure the amount of carbon dioxide that dissolves in the solution. You can then calculate the solubility of carbon dioxide in sodium hydroxide by dividing the amount of CO2 that dissolves by the volume of the solution.
What is the Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
Why does zinc hydroxide dissolve in excess dilute sodium hydroxide?
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.
