Why is it that apple slices can be kept from browning by brushing them with lemon juice. infer what role lemon juice plays in this case?
Ascorbic acid from lemon juice act as a preservative; the reaction between polyphenol oxidase (an enzyme) with oxygen from air is stopped.
What is the relationship between a catalyst and an inhibitor?
A catalyst speeds up a reaction and an inhibitor slows down a reaction
How does using lemon juice as an inhibitor help to preserve fruit?
It helps it by the fruit not getting brownish or rotten
Can a catalyst be used in place of an inhibitor?
umm no. they are opposites. a catalyst will speed up a reaction and an inhibitor will slow it down.
What is the opposite of a catalyst?
In chemistry it is Inhibitor
What is the purpose of an inhibitor in a chemical reaction?
The inhibitor interferes with the catalyst in a chemical reaction.
Is inhibitor and negative catalyst are same things?
A negative catalyst is added to a reaction to slow down a process as does an inhibitor. From this you could say that they are equivalent.
Brushing the cut edges of fruit with lemon juice can prevent the darkening efffect that contact with air can cause?
Adding lemon juice the surface pH of the fruit is modified; this is an anti-oxidative action.
What is the difference between a catalyst and an inhibitor?
Catalyst: a substance which promote and help a chemical reaction. Inhibitor: a substance which greatly reduces the rate of a chemical reaction.
What material is used to decrease the rate of a reaction?
An "inhibitor" (aka negative catalyst) slows or blocks a chemical reaction. In some cases this can also be called a deterrent or a retardant. The term anticatalyst(anti-catalyst) refers to blocking the action of a catalyst.
What is the opposite reaction of a Catalyst?
The opposite of a catalyst is an inhibitor, something that suppresses or slows a reaction.
The difference between catalyst and inhibitor?
A catalyst lower the activation energy (speeds up the reaction) while an inhibitor increases the activation energy (slows it down).
