The egg in HCl reacts violently as the calcium carbonate on the outer surface of egg is dissolved. This is what actually happens :
The egg in the hydrochloric acid is lighter, because the gas bubbles provide a floatation device, than the acid so it stayed at the top. The bubbles occurred because the calcium carbonate on the egg shell reacted with the acid. Carbon dioxide bubbles are produced, causing the egg to rotate and spin. The carbon dioxide bubbles on top of the eggs break. In the meantime more bubbles are attached to the bottom of the egg. These bubbles now cause the egg to spin and repeat the process.
The bubbles attached to the egg also made it less dense.
After this experiment, the egg will not have a shell. It will have dissolved.
then when you place this egg in water, Osmosis takes place. Well, the egg is 90% water. So now when you keep the egg in water it kind of pushes the egg membrane. Basically, water is flowing into the egg and the egg swells as the water enters it.
It dissociates into ions by this equation: HCl + H2O --> H3O+ + Cl-
Putting an acid in water will result in dissociation. For example, when hydrochloric acid is put in water, HCl becomes H+ (hydronium ions) and Cl- (chloride ions). The degree to which the acid dissociates determines it's strength.
Formation of magnesium chloride: Mg + 2 HCl -> MgCl2 + H2
You take an iron ball and put HCL in it and then wait for a week and you will see what happens
The egg will decrease in size (water will exit) if the shell is removed by some means before the egg is placed in the solution. If the shell has not been removed, however, not much will happen as the shell is basically impermeable.
It dissociates into ions by this equation: HCl + H2O --> H3O+ + Cl-
It will get wet.
It will get wet.
It floats.
I think that the egg shrivels up
the outside of the egg will be hard because the egg will be boiling
The egg should have its water or substance in the egg come out through the cell membrane. :)
The vinegar will disintegrate the egg shell and the salt will suck out all the water and shrivel the egg.
the egg decreases in mass because the water moves out of it through the membrane, this happens because water goes from low high to concentration. this is called osmosis.
When an egg is submerged under tap water it will float. This is because water is more dense than the egg.
If you put an egg in salt water for a week, the egg will begin to undergo osmosis. The salt concentration in the water will cause water to move out of the egg, resulting in the egg shrinking and becoming smaller in size. The egg's membrane may also become translucent or appear to be semi-transparent.
the egg will turn brown
