Why is ammonia gas not collected over water?
Because ammonia is quite soluble in water, so that not all of the gas produced could be collected over water.
How do you prepare acetate buffer pH 3.5?
Dissolve 25g of Ammonium acetate in 25ml of water and add 38ml of 7M hydrochloric acid. Adjust the pH of the solution to 3.5 with either 2M hydrochloric acid or 6M ammonia and dilute with water to 100ml
Why does the pH of an acetate buffer increases after dilution with water?
The pH of water is approximatly 7 (a neutral pH), and the acetate buffer has an acidic pH (less than 7) so when you add distilled water to the buffer the pH will increase.
What is the solute and solvent in household ammonia?
Ammonia is the solute and the solvent is the water.
Is ammonia mlecule NH3 more polar than water molecule?
no, water is more polar than ammonia.
Why is ammonia-sodium chloride buffer solution is added in the determination of total hardness of water?
ammonia has a strong smell?
What are the different physico chemical parameters of water?
pH alkanity hardness ammonia etc.........
How does ammonia affect the pH balance of the water in an aquarium what can be done to fix this problem?
Ammonia is a base. To fix it, perhaps try adding buffer to the water. Just as a side note, the ammonia is actually a product of the fish. Fish pee pure ammonia because of the abundance of water in their system.
What does buffer and added hardness do for a saltwater pool?
Buffer and added hardness do the same thing in a salt water pool as in a fresh water pool. The buffer (sodium bicarbonate aka bicarbonate of soda) stabilizes the pH of your pool so that addition of acid or base doesn't change the pH very much. The hardness, mostly Calcium, helps achieve water balance to make the pool neither deposit (precipitate) excess Calcium Carbonate to your pool surfaces nor corrode (remove) Calcium from your plaster pool surface. The combination of pH, Total Alkalinity (adjusted for Cyanuric Acid), Calcium Hardness, temperature and Total Dissolved Solids determines whether your water is balanced. Just keep these values near their recommended amounts for your pool and you should be fine. If you're a techie and want the full formulas, do a Google search for "Langelier Saturation Index".
What is the need for an ammonical buffer solution in the determination of hardness of water by edta titration?
during the complexometric titration using edta it is very necessary to maintain the ph of the solution near about 10 so we use ammonium chloride buffer if we will not use this buffer dring the titration ph of sol. will ho lower side
What is difference between carbonate and noncarbonate hardness?
Carbonate hardness is the measure of hard ions associated with carbonate and bicarbonate anions contained in the water.Noncarbonate hardness is the portion of total hardness in water that is not produced by carbonates, but primarily by sulfate anions.
What is the average hardness of a bottle of water?
Total hardness=(Ca2+)*(combining weight of CaCO3/combining weight of Ca2+) +(Mg2+)(combining weight of CaCO3/combining weight of Mg2+)
Why is water a good pH buffer?
Water is not a good pH buffer.
What should the KH be in a freshwater tank?
The hardness of your water would depend on the species of fish you intend to keep. African Cichlids need hard water with a very high GH/KH (total hardness) but fish from the Amazon need soft water with very low GH/KH (total hardness). I would advise you to always independently research what water parameters are required for whatever species you wish to keep.
In this procedure a 10x buffer is used if you have a 5x buffer and you want a total volume of 200ul what dilution would you perform to achieve the desired 1x concentration of buffer?
10x to 1x is a 1:10 dilution Therefore, add 1 part buffer, 9 parts DI-water If 100uL is 10uL (1 part buffer) and 90uL (9 parts DI-water) Then, 200ul (100 x 2) is 20uL (1 part buffer) and 180uL (9 parts DI-water)
Which does not cause hardness of water?
Magnesium sulfate (MgSo4) does not cause hardness of water.
Wat salt is responsible for temporary and permanent hardness of water?
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
