What is the horizantal line test and vertical line test?
Horizonatal line test is a test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one. A one-to-one function is a function where every element of the range correspons to exactly one element of the domain. Vertical line test is a test used to determine if a function is a function or relation. If you can put a vertical line through graph and it only hits the graph once, then it is a function. If it hits more than once, then it is a relation.
If a function is positive at a test number does the function has no zeros?
false!
What is the relationship between chest circumference and lung function test?
what is the relationship between chest circumference and lung function test
How do you use the vetical line test to determine a function?
f(x) = x2 This is a function by the vertical line test because a vertical line drawn through this function will only intersect the function at one point
When is it not a function?
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
What is the composition of fehling's solution and what are its functions?
Fehling's solution consists of two separate solutions: Fehling's A (copper sulfate) and Fehling's B (potassium tartrate and sodium hydroxide). Fehling's solution is commonly used to test for the presence of reducing sugars in a solution, such as glucose. The copper ions in Fehling's solution are reduced by the reducing sugars, leading to the formation of a red precipitate of copper(I) oxide.
Why do you have to keep fehling's A with fehling'a B?
Fehling's A and Fehling's B are used together in the Fehling's test to detect the presence of reducing sugars, such as glucose. Fehling's A is a copper(II) sulfate solution, while Fehling's B is a complex solution of potassium sodium tartrate and sodium hydroxide. They work together to oxidize the sugar, causing a color change that indicates the presence of a reducing sugar.
What is the composition of fehling's solution?
Fehling's solution is made up of two separate solutions: Fehling's A (copper sulfate solution) and Fehling's B (potassium sodium tartrate and sodium hydroxide solution). When combined in equal parts, these solutions are used to test for the presence of reducing sugars like glucose in a chemical sample.
Does the starch reduce the fehling's solution?
No, starch does not reduce Fehling's solution. Starch is a polysaccharide composed of glucose molecules linked together, whereas Fehling's solution is a complex of copper sulfate, sodium hydroxide, and potassium sodium tartrate used to test for the presence of reducing sugars. Starch is not a reducing sugar and therefore will not react with Fehling's solution.
What is fehlings solution?
Fehling solution "A" is copper sulphate solution and Fehling solution "B" is a solution of sodium potassium tartrate and NaOH.
What chemical formula for Fehlings reagent?
The Fehling A solution contain copper sulfate.The Fehling B solution contain sodium potassium tartrate and sodium hydroxide.
What is the function of Fehling's test?
Fehling's test is used to detect the presence of reducing sugars in a solution. It involves the reaction of the reducing sugar with Fehling's solution, resulting in the formation of a colored precipitate if a reducing sugar is present. This test is commonly used to test for the presence of sugars like glucose and fructose.
Why benzaldehyde doesn't give fehling solution test?
Benzaldehyde does not give a positive Fehling test because it is an aromatic aldehyde, which lacks the alpha-hydrogen necessary to undergo oxidation. In the Fehling test, aldehydes with alpha-hydrogens are oxidized to carboxylic acids, and since benzaldehyde does not have alpha-hydrogens, it does not undergo this oxidation reaction.
Does formalin give positive Fehling's solution test?
Formalin gives a positive Fehling's solution test.
Does formic acid fehling's test?
No, formic acid does not react in the Fehling's test. The Fehling's test is specifically used to test for the presence of reducing sugars. Formic acid is a carboxylic acid and does not possess a reducing sugar functionality.
Is fehling test positive for gluconic acid?
No. Fehling's test is positive for glucose which forms gluconic acid as the product.
What is the difference between fehling and Benedict test?
Both Fehling's and Benedict's tests are used to detect the presence of reducing sugars in a solution, such as glucose. The key difference lies in the composition of the reagents: Fehling's solution is made up of separate A and B components that need to be mixed before testing, while Benedict's solution is a single solution containing the necessary components. Additionally, Fehling's solution is more sensitive than Benedict's solution.
