How do you make bordeaux mixture?
To make bordeaux mixture, mix together copper sulfate and hydrated lime in water. The typical ratio is 4 parts copper sulfate to 4 parts hydrated lime to 100 parts water. Ensure everything is fully dissolved before using it as a fungicide in the garden.
What technique should be used when changing some copper sulfate solution into solid copper sulfate?
The most common technique for converting a copper sulfate solution into solid copper sulfate is through evaporation. This involves heating the solution to allow the water to evaporate, leaving behind solid copper sulfate crystals. The process can be carefully monitored to ensure the crystallization of pure copper sulfate.
Why does copper sulphate turn green when iron is added?
When iron is added to copper sulfate, the sulfate ionbreaks away from copper, and combines with iron to form Ferrous Sulfate, which is green in color. It is a single displacement reaction =CuSO4 + Fe ----> FeSO4 + Cu
What concentration would you mix copper sulphate for cow foot mat?
For a cow foot mat, a common concentration for mixing copper sulfate is typically around 1-3% (10-30 grams of copper sulfate per liter of water). This concentration is effective for providing the necessary properties without being overly harsh. Always ensure to follow local guidelines and regulations regarding the use of copper sulfate in agricultural applications.
When the equation below is balanced the CuSO4 ZnSO4 Cu?
To balance the equation involving copper sulfate (CuSO4) and zinc sulfate (ZnSO4), we need to ensure that the number of atoms for each element is the same on both sides. The balanced equation is: ( \text{CuSO}_4 + \text{Zn} \rightarrow \text{ZnSO}_4 + \text{Cu} ). In this reaction, one mole of copper sulfate reacts with one mole of zinc to produce one mole of zinc sulfate and one mole of copper.
Why was the copper II oxide added in excess to dilute sulfuric acid to form the soluble salt copper II sulphate?
Copper II oxide was added in excess to ensure that all the sulfuric acid reacted, forming water and copper II sulfate. This method helps to avoid any excess sulfuric acid remaining in the solution, ensuring that all copper II oxide reacts completely to form the desired copper II sulfate salt.
How many copper sulphate ppm for algae control?
The recommended dosage of copper sulfate for algae control is typically between 0.2 to 0.4 ppm (parts per million). However, it is important to perform a water test and consult a professional before applying copper sulfate to ensure safe and effective treatment. Overdosing can harm aquatic life and cause water quality issues.
What do you use to measure 0.5g of copper sulphate?
weigh out 0.5 g of copper sulphate on a weighing balance. u can use weighing paper to weigh the substance.
How do you make pure copper?
Pure copper can be made by electrolyzing a copper sulfate solution using copper electrodes. During this electrolysis process, copper ions in the solution migrate towards the negative electrode and deposit as solid copper, resulting in pure copper being formed. It is important to use high-purity chemicals and maintain controlled conditions to ensure the purity of the final copper product.
What substance is used as a control in a Biuret test?
Biuret reagent is made up of sodium hydroxide and copper sulphate.
Is copper sulphate fumes dangerous?
Yes, it can react with (oxidise) more reactive metals than copper is. Eg. Zn, Fe, Al etc. (Let Me be the more reactive metal with oxidation value of + 'n' ( = ion charge when oxidised)2 Me + n Cu2+ --> 2 Men+ + n Cu
Why is copper used for the electrodes?
Because sulphate ions move towards anode (copper) the copper of anode donates 2 electrons to external circuit and becomes +2 ions and moves to the solution so copper anode continuously dissolves in solution.
