go for a wee!:)
cobalt chlorideCompound that exists in two forms: the hydrated salt (CoCl2.6H2O), which is pink, and the anhydrous salt, which is blue. The anhydrous form is used as an indicator because it turns pink if water is present. When the hydrated salt is gently heated the blue anhydrous salt is reformedcobalt chlorideCompound that exists in two forms: the hydrated salt (CoCl2.6H2O), which is pink, and the anhydrous salt, which is blue. The anhydrous form is used as an indicator because it turns pink if water is present. When the hydrated salt is gently heated the blue anhydrous salt is reformedCobalt chloride in simple terms.When the cobalt chloride has no water (ANHYDROUS) it is BLUE. when water is present then the anhydrous cobalt chloride becomes HYDRATED cobalt chloride and it is PINK.
What happens when u would heat a solution of salt water, the water would evaporate and leave the salt right, the combined mass of salt water is 2.39, but after heating 1.39. find the mass of water 2.39 - 1.39 = 1, then u would take 1/2.39times by 100. your answer is 41.8%.
To determine the percent by mass of water in the hydrated salt, we first need to find the mass of water lost during heating. The mass of water lost is 9.10 g - 5.41 g = 3.69 g. The percent by mass of water is then (3.69 g / 9.10 g) * 100% = 40.6%.
Hydrated salt-Salt with water of crystallization are called hydrated salt. Those water are bonded with dative bonds though.Anhydrous salt-Salt which have lost their water of crystallization are called anhydrous salt.
The mass percent of water would be too high if heating was insufficient to remove all of the water from the hydrated salt, as some water would still be present in the compound.
Sodium chloride (NaCl) is not a hydrated salt.
Sodium chloride (NaCl) is not a hydrated salt.
A hydrated salt contain water of crystallization.
Yes, when you add water to salt, the salt can absorb some of the water molecules, creating a hydrated salt solution. The water molecules surround the individual salt ions, helping to dissolve the salt.
FeSO4 or FeSO4.7H20
On heating, hydrated salts lose their water of crystallization and as a result, the crystals lose their shape and colour and change to a powdery substance.
No.
Yes, Epsom salt, chemically known as magnesium sulfate heptahydrate, is a hydrated crystal. It contains water molecules within its structure, giving it a crystalline form.
Sodium chloride hasn't hydrates but it is hygroscopic.
If the original sample is unknowingly contaminated with a second anhydrous salt, the reported percent water in the hydrated salt will be too low. This is because the presence of the anhydrous salt will increase the overall weight of the sample without contributing to the water content calculation, leading to a lower reported percentage of water in the hydrated salt.
To obtain salt water is evaporated.
You obtain salt water by letting the sea water evaporate.
