The purpose of digestion process in gravimetric analysis is to: 1. O decrease the particle size of the precipitate 2. O evaporate the solvent 3. O dry the precipitate 4. O coagulate the precipitate
During the investigation, the student found that the size of the sugar also effects the solubility of the sugar. Give one inference for the above observation. *
A saturated silver carbonate solution (1.0 L) is preparedat 5 °C and filtered to separate the undissolved phase. The filtrate is treated at 25 °C withhydrochloric acid, whereby the carbonate ions decompose and carbon dioxide is formed. The measurement shows thatthe level of carbon dioxide above the reaction vessel is 600 ppm. All carbon dioxide gas formed is collected ina test tube with a volume of 19 mL, and at 25 °C the pressure is measured to be 114 mmHg. CalculateKsp for silver carbonate at 5 °C.
In bromine water test Procedure: -Add 3 ml of phenol and ethanol in separate test tube-Add 10 ml of water to each test tubes-Transfer to bigger test tubes-For phenol and ethanol, Add bromine water drop by drop until bromine color persists MUST DO: Observe formation of precipitate P.s I provided photos for better visualization of the overall result procedure, I just need a further and detailed answer based on observation. If answered properly I will upvote, I promise tyyy. Please do focus on the formation of precipitate, thank youuu The first photo is the phenol one (colored one) and the second one is the ethanol (clear one)

When performing an extraction with the solvent pair: H,O and ethyl acetate (E1OAC), two separate layers (aqueous and organic) form. What is the order of the layers and why? 1) The aqueous layer is on top and the organic layer is on the bottom. This is due to the aqueous layer being more dense O 2) The aqueous layer is on top and the organic layer is on the bottom. This is due to the water layer being more dense O 3) The aqueous layer is on top and the organic layer is on the bottom. This is due to the organic layer being more dense 04) The organic layer is on top and the aqueous layer is on the bottom. This is due to the water layer being more dense
