Best Answer

Monohydrate: MgNH4PO4*H20

MM of MgNH4PO4*H20= 173.28

MM of P=30.97

(30.97/173.28) *100 = 17.87%

Anhydrous:MgNHPO4

MM of MgNHPO4=137.29

MM of P= 30.97

(30.97/137.29) *100= 22.56%

Does citric acid expire?

It doesnt really expire. It's original form is anhydrous, meaning no water molecules. Over time, it becomes monohydrate (plus 1 molecule of water) upon reaction with air.


How can convert sodium dihydrogen phosphate monohydrate to sodium dihydrogen phosphate anhydrous?

The ratio pf molecular weights is 124/106 mono/anh. Most uses of sodium carbonate need not be accurate to closer than 1% and many need not be closer than 10%. Anhydrous carbonate tends to become monohydrated by taking moisture from the atmosphere.


Would Epsom salt table salt or baking soda make the better desiccant and why?

The answer is Epsom salt. It is extremely hygroscopic when converted from the Heptahydrate form to the Anhydrous form and is an excellent desiccant. Instructions for making Anhydrous Magnesium Sulfate from Magnesium Sulfate Heptahydrate (Epsom Salts) are as follows - MgSO4 • 7H2O ==>> MgSO4 Epsom Salts is easily converted to Anhydrous Magnesium Sulfate by heating in an oven at temperatures between 200°C and 250°C . 150°C - Magnesium Sulfate Heptahydrate is converted to Magnesium Sulfate Monohydrate. 200°C - Magnesium Sulfate Monohydrate is converted to Anhydrous Magnesium Sulfate. 250°C - Complete dehydration of Epsom salts occurs yielding the desired Anhydrous Magnesium Sulfate to be used as a desiccant. 1124°C - Sublimates to MgO, SO2, SO3 before MP (Melting Point). MgSO4.7H2O = 246.4564 molecular weight MgSO4 anhydrous = 120.36 molecular weight 120..36 / 246.45 = 48.83% 246.45 / 120.36 = 204.76% Anhydrous MgSO4 absorbs 204.7% it's weight in water. As a comparison, Silica Gel absorbs 160%.


What is difference between citric acid mono and citric acid anhydrus?

Citric acid monohydrate has a single molecule of water attached to each molecule of citric acid, whereas citric acid anhydrous has been dried so has no water at all.


Difference between mono-hydrate citric acid anhydrous citiric acid?

Monohydrate citric acid has a single (=mono) molecule of water (=hydrate) attached to each molecule of citric acid, whereas anhydrous citric acid has been dried so has no water at all (no water = anhydrous).


Is water anhydrous?

no. Water is not Anhydrous. Anhydrous means little or no water at all.
