To determine the limiting reagent between CuSO₄ and NaOH, we first need to look at the balanced chemical equation for the reaction, which is:
[ CuSO₄ + 2 NaOH \rightarrow Cu(OH)₂ + Na₂SO₄ ]
According to the stoichiometry, 1 mole of CuSO₄ reacts with 2 moles of NaOH. First, calculate the moles of CuSO₄ and NaOH. Assuming the molar mass of CuSO₄ is approximately 159.61 g/mol, 638.44 g of CuSO₄ corresponds to about 4.00 moles. For 240.0 g of NaOH (molar mass ≈ 40.00 g/mol), this is about 6.00 moles. Since 4.00 moles of CuSO₄ would require 8.00 moles of NaOH but only 6.00 moles are available, NaOH is the limiting reagent.
Acidified CuSO4 is used as a reagent in the Fehling's test to detect the presence of reducing sugars in a solution. When a reducing sugar is present, it reduces the blue Cu2+ ions in the CuSO4 solution to red-brown Cu2O precipitate, indicating a positive result.
Copper (II) sulfate is represented by the formula CuSO4. It is a chemical compound made up of one copper ion (Cu2+) and one sulfate ion (SO42-). Copper sulfate is commonly used in agriculture as a fungicide and in chemistry as a reagent for various reactions.
CuSO4 · 5H2O has 5 water molecules attached to each CuSO4 molecule.
The ratio of moles of CuSO4 to moles of water in CuSO4•5H2O is 1:5. This is because there is one mole of CuSO4 for every five moles of water in the compound.
CuSO4 is the chemical formula of copper(II) sulfate.
Sodium hydroxide is the limiting reagent.
CuSO4 is copper (II) sulfate. The balanced equation for CuSO4 with water is CuSO4 + H2O reacts to become Cu+2 + HSO4-2 + OH-.
When CuSO4 reacts with KCN, cyanide ion (CN-) replaces sulfate ion (SO4^2-) to form copper cyanide (Cu(CN)2) and potassium sulfate (K2SO4).
Copper sulfate dissolves in water, it does not react.
Acidified CuSO4 is used as a reagent in the Fehling's test to detect the presence of reducing sugars in a solution. When a reducing sugar is present, it reduces the blue Cu2+ ions in the CuSO4 solution to red-brown Cu2O precipitate, indicating a positive result.
To solve this problem, start by writing a balanced chemical equation for the reaction between Al and CuSO4. The molar ratio from the balanced equation indicates that 1 mole of Al reacts with 3 moles of CuSO4 to form 3 moles of Cu. Calculate the moles of Al and CuSO4 in the given masses, determine the limiting reactant, and use stoichiometry to find the mass of metallic Cu produced.
Benedict's reagent is an aqueous solution of copper (II) sulfate, sodium carbonate, sodium citrate dihydrate and 2,5-difluorotoluene.
The formula CuSO4 stands for copper(II) sulfate, which is a chemical compound composed of copper, sulfur, and oxygen. It is commonly used in agriculture as a fungicide and in schools as a reagent for various chemistry experiments.
When copper sulfate (CuSO4) reacts with hydrochloric acid (HCl), copper chloride (CuCl2) and sulfuric acid (H2SO4) are formed as products. The balanced chemical equation for this reaction is CuSO4 + 2HCl -> CuCl2 + H2SO4.
Anhydrous copper sulfate is CuSO4, while water is H2O. When anhydrous copper sulfate reacts with water, it forms hydrated copper sulfate, which is CuSO4·5H2O.
The reaction between copper oxide (CuO) and sulfuric acid (H2SO4) produces copper sulfate (CuSO4) and water (H2O). The balanced chemical equation for this reaction is: CuO + H2SO4 -> CuSO4 + H2O
This ratio is 1:2.
