Does copper sulphate dissolve better in cold water or in warm water?
Copper sulfate dissolves better in warm water because higher temperatures typically increase the solubility of solids. Warm water has more kinetic energy, allowing the copper sulfate particles to break apart more easily and mix with the water molecules.
What is the largest mass of copper sulphate which can be dissolved in 50g of water at 60 degrees centigrade?
The solubility of copper sulfate in water at 60 degrees Celsius is approximately 203 g/L. Therefore, in 50g of water, the maximum mass of copper sulfate that can dissolve would be 203g/L x 0.05 L = 10.15g.
What is copper sulfates relative formula mass?
The anhydrous copper sulfate (CuSO4) has a molar mass of 159,62.
Why does copper sulfate change mass when heated?
Solid copper appears to gain mass when heated in air, because the copper reacts with oxygen in the air to form copper oxide. However, the actual mass of the copper does not increase; the mass of the solid increases by a value equal to the mass of oxygen removed from the air.
Yonas has 44.78 g of copper II sulfate How many moles does he have?
To find the number of moles of copper II sulfate Yonas has, you need to divide the given mass by the molar mass of the compound. The molar mass of copper II sulfate is 159.61 g/mol. 44.78 g / 159.61 g/mol = 0.281 moles of copper II sulfate.
If add water to a copper sulfate crystal will it get larger?
Copper(II) sulfate can fom 3 hydrates; the molar mass increase from the anhydrous salt to heptahydrate.
Does hydrated copper sulphate increase the mass?
When hydrated copper sulfate is heated, it loses water molecules and forms anhydrous copper sulfate, which has a lower mass due to the removal of water. So, the mass would decrease upon heating hydrated copper sulfate.
What is the percentage of water in hydrated copper sulphate?
Hydrated copper sulfate, CuSO4·5H2O, contains 36.10% water by mass.
Suppose 2.3754g of copper-II sulfate pentahydrate is heated to drive off the water of crystallization Calculate what mass of anhydrous salt will remain?
The gram formula unit mass of copper (II) sulfate pentahydrate is 249.68. The gram formula unit mass of water is 18.015. Therefore, the mass of water of crystallization present in 50.0 g of copper (II) sulfate pentahydrate is: 50[5(18.015)/249.68] or 18.0 g, to the justified number of significant digits. (Note that the prefix penta- means five)
What happens to the density of water when copper sulfate is dissolved in it?
In general when you dissolve something in water the density of the solution will be greater than the density of the original water. This is because the solute (in this case, copper sulfate) will take up space between the water molecules, increasing the mass of the solution without increasing the volume. The density is calculated as mass divided by volume, so increasing the mass without increasing the volume will increase the density.
What happens when add water to copper sulphate?
When water is added to copper sulfate, the copper sulfate dissolves in water to form a blue-colored solution. This is a physical change as the copper sulfate molecules remain unchanged, only dispersing evenly in the water.
Does copper sulphate dissolve better in cold water or in warm water?
Copper sulfate dissolves better in warm water because higher temperatures typically increase the solubility of solids. Warm water has more kinetic energy, allowing the copper sulfate particles to break apart more easily and mix with the water molecules.
How many grams of copper(II) sulfate pentahydrate would you need to measure in order to have 10.0 grams of anhydrous copper (II) sulfate?
To calculate this, you would need to consider the molar masses of copper(II) sulfate pentahydrate and anhydrous copper(II) sulfate. Copper(II) sulfate pentahydrate has a molar mass that includes water molecules, so you need to determine the molar mass difference between the two compounds. Using this information, you can calculate the amount of copper(II) sulfate pentahydrate needed to obtain 10.0 grams of anhydrous copper(II) sulfate.
How do you calculate the molar mass of copper II sulfate pentahydrate?
To find the molar mass of copper (II) sulfate pentahydrate, calculate the individual molar masses of each element present (Cu, S, O, and H) from the periodic table, and then multiply by the respective subscript in the formula. Add up the molar masses of copper (II) sulfate (CuSO₄) and five water molecules (5H₂O) to get the molar mass of copper (II) sulfate pentahydrate.
What is the largest mass of copper sulphate which can be dissolved in 50g of water at 60 degrees centigrade?
The solubility of copper sulfate in water at 60 degrees Celsius is approximately 203 g/L. Therefore, in 50g of water, the maximum mass of copper sulfate that can dissolve would be 203g/L x 0.05 L = 10.15g.
What is copper sulfates relative formula mass?
The anhydrous copper sulfate (CuSO4) has a molar mass of 159,62.
How many grams of copper sulfate would you heat to produce 29.8g of water?
Well, darling, to produce 29.8g of water, you'd need to heat 249.9g of copper sulfate pentahydrate. When you heat it, the water molecules will be driven off, leaving you with just the copper sulfate. Just make sure to wear your safety goggles, we don't need any accidents in the name of science!
