∙ 14y agoSodium Thiosulphate is Na2S2O3 and water is H2O.
Water molecules are attracted to sodium chloride because water is a polar charge. Slightly positive and slightly negative ends on H2O, the sodium chloride Na+ and Cl- attracts to the opposing charge on the water molecule
Water. Butyl alcohol's carbon chain length decreases its polarity and thus its ability to dissolve polar compounds.
The chromate ion (CrO4-2) has yellow colour so all the chromate compounds including silver chromate is yellow in colour.
No
Yes, yellow solutionDid you know that (almost) all Sodium salts are soluble in water?
There are four water molecules bound to Sodium Chromate
chromic acid + sodium carbonate -> sodium chromate + water + Carbon Dioxide
The term trihydrate refers to the fact that three molecules of water are associated with each formula unit of sodium acetate. The formula unit for sodium acetate trihydrate is NaC2H3O2‧3H2O.
This is a neutralization reaction. This reaction should result in producing a salt and water. Sodium chromate is the salt in this instance.
Magnesium chromate remains insoluble in water.
No, lead chromate is insoluble in water
Sodium Thiosulphate is Na2S2O3 and water is H2O.
The crystalline structure of sodium chloride is face-centered cubic.
Take a known weight of the sodium carbonate, heat it to above 100ºC to drive off the water, and keep heating until a constant weight is obtained. The difference between initial weight and final weight is the mass of water attached. Convert this to moles and then to molecules and relate this to 1 formula unit of Na2CO3.
The ph of the water is increased and the water becomes more alkaline. Water molecules break sodium hydrogen carbonate molecules to ions.
