What is the chemical formula for sodium thiosulfate and water?
Sodium Thiosulphate is Na2S2O3 and water is H2O.
Why are water molecules attracted to sodium chlorine?
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
Which of water and butyl alcohol is a better solvent for sodium chromate?
Water. Butyl alcohol's carbon chain length decreases its polarity and thus its ability to dissolve polar compounds.
What color is Silver chromate dissolved in water?
The chromate ion (CrO4-2) has yellow colour so all the chromate compounds including silver chromate is yellow in colour.
Is silver chromate soluble in water?
No
Does sodium chromate dissolve in water?
Yes, yellow solutionDid you know that (almost) all Sodium salts are soluble in water?
What is the Number of water molecules bound per formula unit of nickel II nitrate?
There are four water molecules bound to Sodium Chromate
What is the chemical reaction between chromic acid and sodium carbonate?
chromic acid + sodium carbonate -> sodium chromate + water + Carbon Dioxide
What is the trihydrate in sodium acetate as trihydrate crystals?
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.
What is formed when sodium hydroxide reacts with chromic acid?
This is a neutralization reaction. This reaction should result in producing a salt and water. Sodium chromate is the salt in this instance.
Magnisium chromate in water?
Magnesium chromate remains insoluble in water.
Determining the number of molecules of crystallization water per formula unit of sodium carbonate?
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.
What is the structure of sodium chloride and water?
The crystalline structure of sodium chloride is face-centered cubic.
What happens when sodium hydrogen carbonate solution is mixed with water?
The ph of the water is increased and the water becomes more alkaline. Water molecules break sodium hydrogen carbonate molecules to ions.
What is the chemical formula for sodium thiosulfate and water?
Sodium Thiosulphate is Na2S2O3 and water is H2O.
Is lead chromate soluble?
No, lead chromate is insoluble in water
What is the dfference between sodium citrate and sodium citrate dihydrate?
two water molecules
