What is a negative reaction for Benedict's?
A negative reaction for Benedict's test would be no color change or a very faint color change after adding the Benedict's reagent to a sample containing reducing sugars. This would indicate that there is a low concentration or absence of reducing sugars in the sample.
Why might a substance taste sweet but give a negative reaction with the Benedict's solution?
A substance could taste sweet due to the presence of natural sugars, while giving a negative reaction with Benedict's solution if the sugar present is a non-reducing sugar. Non-reducing sugars like sucrose do not react with Benedict's solution because they do not have the free aldehyde or ketone groups required for the reaction.
Which sugar gives a negative reaction to Benedict reagent?
Sucrose gives a negative reaction to the Benedict's reagent test because it is a non-reducing sugar. Benedict's reagent is used to test for the presence of reducing sugars, which have the ability to reduce the copper ions in the reagent. Since sucrose does not have this ability, it does not give a positive reaction.
What is an adverse reaction?
an allergic or negative reaction to a substance. Hahaha, I feel clever now :)

What is it called and what happens then negative and positive are mixed together?
When negative and positive are mixed together, it is called a neutralization reaction. In this reaction, the positive ions from one substance combine with the negative ions from the other substance to form a product that is electrically neutral.
The bodies negative reaction to a particular substance?
octane bribine octane bribine
What is the name of the bodily reaction that is negative to a substance that is inhaled injected or swallowed?
Adverse.
Why did the potato juice test negative in the benedict's reagent test?
The potato juice likely tested negative in the Benedict's reagent test because it does not contain reducing sugars, such as glucose or fructose, which are necessary to form a positive reaction with Benedict's reagent. Potatoes primarily consist of starch, a polysaccharide that is not a reducing sugar, explaining the negative test result.
A chemical change in which a substance becomes more negative?
The chemical change in which a substance becomes more negative could be the ionization of the substance. Means that the substance becomes more negatively charged and that is due to it being ionized. It tends to gain more electrons in order to fill its valence shell to become a stable substance.
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
What is a chemicall reaction?
A chemical reaction is a reaction in which a substance is turned into another completely different substance
