What is the pH of copper sulfate?
The pH of a copper sulfate solution depends on its concentration. Typically, a 1% solution of copper sulfate has a pH of around 3-4, making it acidic.
What is pH of potassium sulfate granular?
Granular potassium sulfate does not have a pH. A pH value can only be given to a solution.
Do insoluble calcium compounds increase the pH of acidic soils eg calcium carbonate and calcium sulfate?
Carbonate will increase soil pH value, because it reacts with acid, but sulfate will not affect the pH.
What is zinc sulphate on the pH scale?
The pH of zinc sulfate water solution is approx. 4,5.
What are the conclusions from testing the Biuret reagent for protein?
The reagent used in the Biuret Test is a solution of copper sulfate (CuSO4) and potassium hydroxide (KOH). The KOH is there to raise the pH of the solution to alkaline levels; the crucial component is the copper (II) ion from the CuSO4. When peptide bonds are present in this alkaline solution, the copper (II) ions will form a coordination complex with four nitrogen atoms involved in peptide bonds. Copper Sulfate solution is a blue colour, but when the copper (II) ions are coordinated with the nitrogen atoms of these peptide bonds, the colour of the solution changes from blue to violet. This colour change is dependent on the number of peptide bonds in the solution, so the more protein, the more intense the change. When the peptides are very short, the solution turns a pink colour, rather than violet.

What is cupric sulfate elements makeup?
Cupric Sulfate is also known as Copper(II) sulfate and is considered a salt. The II and the -ic suffix for the copper represent 2 electrons lost (creating a doubly charged Copper positive ion [cation]) to the Sulfate molecule, which acquires a negative 2 charge and is an anion. Salts are written with the electron donor first and the electron receiver second. In anhydrous form there is no water (There is no hydrogen so no pH) --and no bright blue crystal Cu2+SO42- In the crystalized form, 5 molecules of water (pentahydrate) becomes part of the structure for each atom of Copper (Cu). The chemical formula is CuSO4•5H2O. Dissolved in solution (water) cupric sulfate is a strong electrolyte and conductor of electricity. Expect an acidic pH of 3.7 to 4.5
What is copper oxides pH?
Copper(I) oxide and copper(II) oxide are both very insoluble in water. In practise i would expect no pH to be detected- however as they are basic oxides if any pH is detected it will be greater than 7.
What is pH of potassium sulfate granular?
Granular potassium sulfate does not have a pH. A pH value can only be given to a solution.
What is the pH level of copper sulfate?
Copper sulphate doesn't have a pH on its own, because it has no H+ ions, however when you form copper sulphate solution in water, H+ ions will dissociate from the water. This would depend on the concentration, do you have any idea what concentration you are using?I think it would be weakly acidic, but you need to know the concentration to give a proper pH
What happens when copper sulfate and sodium hydroxide mix?
You'll get hydrated Cu ions (blue colored): [Cu(H2O)6]2+ (which will partially protolyse with water, being weak acidic) and SO42- ions: So the solution is blue and slightly acidic (1M sol'n pH= 4)
Does aluminum sulfate raise or lower the pH level of paint washwater?
Aluminum sulfate raises the pH level of paint washwater.
What is the pH level of ammonium sulfate?
pH of 0.1M solution is 5.5.
What is the pH of salt?
The pH of Magnesium Sulfate is: 4.5 (3.5 to 6.5).
Do insoluble calcium compounds increase the pH of acidic soils eg calcium carbonate and calcium sulfate?
Carbonate will increase soil pH value, because it reacts with acid, but sulfate will not affect the pH.
