Dissolving and hydratation reaction (this gives the blue color of Cu hydrated ions)
CuSO4 + 4H2O --> Cu(H2O)42+ + SO42-
followed by two differend protolysis reactions, of which the first is relatively stronger acidic than the second (wich is very weakly basic):
Ferrous ammonium sulfate is prone to oxidation, forming insoluble iron hydroxides. Preparing the solution in an acidic medium helps to prevent oxidation of ferrous ions to ferric ions, ensuring the stability of the solution and enhancing its accuracy for titrations or other analytical procedures. Additionally, the acidic medium helps to maintain the solubility of the compound.
It depends on the metal in the green sulphate solution.
Acetic acid (CH3COOH) is acidic because it donates a proton (H+) in solution. The presence of this proton gives acetic acid acidic properties.
The hydrogen ion (H+) is responsible for acidic properties. In acidic solutions, there is a higher concentration of H+ ions, which gives the solution its characteristic sour taste and ability to conduct electricity.
The red or pink color in an acidic solution is typically due to the presence of an acid-base indicator called phenolphthalein. In acidic conditions, phenolphthalein turns colorless, while in basic conditions it turns red or pink.

When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.

Acidic. It is basically produced by an acetic acid bacteria "Acetobacter".
The acidity of citric acid is due to its ability to release hydrogen ions (H+) when in solution. This release of hydrogen ions is what gives citric acid its acidic properties.
An acid is a substance that releases hydrogen ions, H+, in an aqueous (water) solution, or a substance that gives up a hydrogen ion to another molecule or ion depending on which definition you use.
M = moles solute/ Liters solution 1 mL= 0.001 L 0.990M x 0.001 L =9.9 x 10^-4 moles CuSO4 9.9 x 10^-4 *2 = 0.00198 solute particles *When you dissolve 1 mole CuSO4 in water, it dissolves into 1 mol of Cu+ ions and 1mol of SO4- ions, which gives you twice as many moles of solute particles- which is why you multiply 9.9 x 10^-4 by 2. Hope this helps
Litmus solution is obtained from lichens. It is used to test whether the solution is acidic or basic.
No, only exces of OH- gives you an alkaline solution and exces of H+ gives you an acidic solution. When they are EQUAL then the solution (water) is NEUTRAL, pH= 7.0
