What will happen if a base is added to water?
When a base is added to water, it will dissociate, releasing hydroxide ions (OH-) into the solution. These hydroxide ions will react with water molecules to increase the concentration of OH- ions and decrease the concentration of H+ ions, resulting in an increase in pH.
What happen when oxalic acid is added to phenolphthalein?
Phenolphtalein is colorless in an acidic medium.
What will happen when phenolphthalein paper is used to test a base?
It will change its colour from white to red on increasing the pH(for bases)
What will happen if solutes are dissolved into a solution?
A solution is obtained.
What solution contains more solute than predicted at a given temperature?
A supersaturated solution contains more solute than predicted at a given temperature. This can happen when a solution is prepared with more solute than can normally dissolve in that solvent at that temperature, creating a metastable state where the excess solute remains dissolved until disturbed.
What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
Is solution x safe to drink with phenolphthalein?
what would happen if scientists were testing to see if a substance was safe to drink and used phenolphthalein as an indicator and what would happen if the test was done using methyl orange
What would happen if I placed a Vial of phenolphthalein into a jar with ammonia?
Nothing will happen... but when you put a drop of the vial in the phenolphthalein, the phenolphthalein will turn into pink... It was just an observation that I saw in our experiment this afternoon
What happens to a solution when a metal oxide dissolves in water?
When a metal oxide dissolves in water, it forms a metal hydroxide solution. This process usually involves the release of hydroxide ions into the solution, resulting in an alkaline pH. The metal hydroxide dissociates into metal cations and hydroxide anions in the water.
What will happen when sulphuric acid is treated with sodium hydroxide solution?
Sodium sulfate is formed as a result of this neutralization reaction.
What would happen when sodium hydroxide is placed in salt water?
When sodium hydroxide is placed in salt water, it will react with the water to form sodium ions and hydroxide ions. The sodium ions will not react with the salt water, but the hydroxide ions will increase the pH of the solution, making it more basic.
What would happen to an animal cell if it was placed into a beaker containing a hypertonic solution?
You need dayan 2 hours
What will happen if water and carbon dioxide mix?
A solution of carbonic acid (containing the ions H+ and CO3-) is obtained.
What will happen if a base is added to water?
When a base is added to water, it will dissociate, releasing hydroxide ions (OH-) into the solution. These hydroxide ions will react with water molecules to increase the concentration of OH- ions and decrease the concentration of H+ ions, resulting in an increase in pH.
What happen when oxalic acid is added to phenolphthalein?
Phenolphtalein is colorless in an acidic medium.
What happen when test solution mix with sodium hydroxide?
When a test solution mixes with sodium hydroxide, a chemical reaction may occur depending on the components of the test solution. Sodium hydroxide is a strong base and can react with acidic components in the test solution, resulting in neutralization and the formation of water and a salt. The reaction may also cause a change in color or precipitation, depending on the specific chemical properties of the test solution.
How does the SN1 reaction in this experiment cause the acid-base indicator phenolphthalein to change color?
In the SN1 reaction, the carbocation intermediate formed is a strong electrophile that can react with nucleophiles present in the solution. When phenolphthalein is exposed to the acidic conditions of the reaction mixture, it becomes colorless due to protonation. As the reaction progresses and the carbocation intermediate reacts with the nucleophile, the acidic conditions decrease, causing deprotonation of phenolphthalein and a color change to pink.
