What is the mass of one mole of hydrated copper sulfate?
250 grams
For example, the weight of a mole of CuSO4•5H2O is 250 grams (this is the molar mass of CuSO4•5H2O). A mole of CuSO4•5H2O contains 5 moles of water (which corresponds to 90 grams of water) as part of its structure. Therefore, the substance CuSO4•5H2O always consists of 90/250 or 36% water by weight.
Does copper II sulfate react with HCl?
The reversible copper sulfate reaction When concentrated hydrochloric acid is added to a very dilute solution of copper sulfate, the pale blue solution slowly turns yellow-green on the formation of a copper chloride complex.
What is the formula for hydrated copper sulfate?

How do you find the mass of a hydrated copper sulfate?
Worked example
- The mass of hydrated copper sulfate = 127.95 g – 125.45 g = 2.50 g.
- The mass of water given off = 127.95 – 127.10 = 0.85 g.
- The percentage of water = 0.85 ÷ 2.50 x 100% = 34%
What happens when Cu reacts with HCl?
Yes, it is obvious that copper will not react with hydrochloric acid for the simple reason it’s below hydrogen in the reactivity series. So, copper cannot replace the hydrogen in HCl to form CuCl2 . Hence, when copper (Cu) reacts with hydrochloric acid (HCl) there will be no reaction.
What is the molar mass of hydrated copper sulfate CuSO4 5h2o?
What is the molar mass of copper II sulfate quizlet?
The molar mass of anhydrous copper (II) sulfate is 159.609 g/mol.
How do you find the molar mass of a hydrate?
The molar mass of the hydrate is the molar mass of the CoCl2 plus the mass of water. Calculate the percent by mass of water by dividing the mass of H2O in 1 mole of the hydrate by the molar mass of the hydrate and multiplying by 100%.
What is the molar mass of copper (II) sulfate?
Molar mass of CuSO 4 is 159.62 g/mol now there is 5.4 grams of dehydrated CuSO 4 (5.4 grams) / (159.62 g/mol) = .034 moles of CuSO 4 Next to get the number of water molecules to copper (II) Sulfate you divide the moles of water by the moles of copper (II) sulfate:
What is hydrated copper (II) sulphate?
These salts are commonly known as hydrated salts. Hydrated Copper (II) sulphate is one of these, as suggested by the use of the word hydrated in its name. Its molecular structure is shown below.
How do you calculate the number of water molecules in copper (II) sulfate?
(5.4 grams) / (159.62 g/mol) = .034 moles of CuSO 4 Next to get the number of water molecules to copper (II) Sulfate you divide the moles of water by the moles of copper (II) sulfate:
What happens when copper sulfate reacts with hydrochloric acid?
Copper sulfate reacts with concentrated hydrochloric acid to give tetrachlorocuprate (II): Copper sulfate is commonly included in teenager chemistry sets. It is often used to grow crystals in schools and in copper plating experiments, despite its toxicity.
