The reaction between an aldehyde and Fehling's reagent (a mixture of copper(II) sulfate and sodium hydroxide) results in the formation of a brick red precipitate of copper(I) oxide. This can be represented by the following equation: Aldehyde + 2Cu2+ (in Fehling's reagent) + 5OH- -> 2Cu2O + 3H2O + 4e-

What is the equation of the aldehyde plus acidified potassium permanganate?

The reaction between an aldehyde and acidified potassium permanganate (KMnO4) typically results in oxidation of the aldehyde to a carboxylic acid. The general equation for this reaction is RCHO + KMnO4 + H+ → RCOOH + MnO2 + K+.


Equation for aldehyde plus acidified potassium permanganate?

Aldehyde + Acidified potassium permanganate (KMnO4) undergoes oxidation, resulting in the formation of a carboxylic acid. The balanced chemical equation for the reaction is: Aldehyde + 2[KMnO4] + 3[H2SO4] → Carboxylic acid + 2[MnSO4] + K2SO4 + 3[H2O].


What is the formula for aldehyde plus NaOH?

The reaction of an aldehyde with NaOH forms sodium salt of the corresponding carboxylic acid. The general equation is: Aldehyde + NaOH -> Sodium salt of carboxylic acid + H₂O.


What reagent might give a characteristic test for ketone and aldehyde?

2,4-dinitrophenylhydrazine (DNPH) can be used to give a characteristic yellow or orange precipitate when reacted with ketones and aldehydes, forming a derivative that is commonly referred to as a 2,4-DNP derivative. This test is known as the Brady's test or 2,4-DNP test.


2no plus o2 equals 2no2 what is the limiting reagent?

The limiting reagent is the reactant that is completely consumed first and determines the maximum amount of product that can be formed. To find the limiting reagent, you need to compare the moles of each reactant to see which one is present in the smallest amount relative to the stoichiometry of the balanced equation.

What is the limiting reagent for the reaction 4Al plus 3O2-2Al2 O3 given that you start with 10.0 grams of Al and 19.0 grams of O2?

To determine the limiting reagent, first convert the grams of each reactant to moles. Then, calculate the mole ratio between Al and O2 in the balanced equation. The reactant that produces fewer moles of product is the limiting reagent. In this case, compare the moles of Al and O2 to determine the limiting reagent.
