When crystals of feso4 are strongly heated the residue obtained is?
The residue obtained from heating crystals of FeSO4 (iron(II) sulfate) is Fe2O3 (iron(III) oxide) and SO2 (sulfur dioxide) gases. This is because the heating process causes the iron(II) sulfate to decompose, releasing water vapor, sulfur dioxide gas, and leaving iron(III) oxide as a solid residue.
What is observed when Fe2SO4 and FeSO4.7H2O are heated strongly?
When FeSO4·7H2O is heated strongly, it loses its water molecules and forms anhydrous FeSO4. The color changes from blue to white or pale green due to the removal of water molecules, and the compound becomes anhydrous iron(II) sulfate (FeSO4).
Why does salt pop when heated?
When salt is heated, the moisture inside it evaporates quickly, causing the salt to crack and pop. This happens because the rapid release of steam generates pressure within the salt crystals, leading to the popping sound.
When a solution is heated and then cooled what happens?
When a solution is heated and then cooled, the solubility of the solute generally increases as the temperature rises, allowing more solute to dissolve. Upon cooling, the solubility decreases, causing the excess solute to precipitate out of the solution in the form of crystals.
What would happen if an aqueous solution of sugar is heated to dryness?
Crystals of sugar are obtained.
What happens when ferrous sulphate crystals are heated and give its balance chemical equation?
When ferrous sulphate crystals are heated, they lose water of crystallization and turn into anhydrous ferrous sulphate. The balanced chemical equation for this process is: FeSO4 • 7H2O (s) → FeSO4 (s) + 7H2O (g)
What is the equation when ferrous sulphate crystal is heated?
When ferrous sulfate heptahydrate crystals (FeSO4·7H2O) are heated, they undergo a dehydration reaction to form anhydrous ferrous sulfate (FeSO4) and water vapor (H2O). The chemical equation for this reaction is: FeSO4·7H2O(s) → FeSO4(s) + 7H2O(g)

What happens to color of copper suphate crystals when heated in a test tube?
The dehydrated copper sulfate is grayish-white.
What happens when ferrous sulphate crystals are heated?
When ferrous sulphate crystals are heated, they lose water molecules and undergo dehydration, forming a white powder known as anhydrous ferrous sulphate. This process is also known as thermal decomposition.
When iodine crystals are heated and cooled in a hot water bath what happens?
When iodine crystals are heated, they sublimate directly from solid to gas without melting. As the hot iodine gas cools, it reverts back to solid form on the cooler surfaces of the container, forming iodine crystals again. This process is called sublimation.
Do Salol crystals form quicker when heated?
they do not form when heated! they form crystals when they are frozen bu a freezer or room tempreature.
Why green color of feso4 changes when heated?
The green color of FeSO4 changes when heated because it undergoes a dehydration reaction. Heating causes the water molecules in the compound to be removed, leading to a change in the oxidation state of iron from +2 to +3, resulting in a color change.
What is the colour of the fumes given off when crystals of iodine are heated?
The fumes given off when crystals of iodine are heated are purple in color.
What happens when ferrous sulphate crystals in boiling tube when heated by spirit lamp?
When ferrous sulfate crystals are heated in a boiling tube with a spirit lamp, they undergo thermal decomposition. The crystals lose water of crystallization and change color from green to white as they form anhydrous ferrous sulfate. This reaction releases water vapor and sulfur dioxide gas.
Why does salt pop when heated?
When salt is heated, the moisture inside it evaporates quickly, causing the salt to crack and pop. This happens because the rapid release of steam generates pressure within the salt crystals, leading to the popping sound.
