Tris buffer as pH by HCl why not for sodium acetate?
The question is in poorly worded. I will assume the question is "why adjust the pH of Tris buffer with HCl and not Sodium Acetate?" I would assume the answer is - because sodium acetate is the conjugate base of a weak acid, and HCl is a strong acid. Also the salts you would be putting into the solution as a result would be different. I think the question is actually, "The pH of Tris is adjusted with HCl, why isn't the pH of sodium acetate adjusted with HCl?". I'm not sure of the answer exactly, but I've always assumed its because if you adjust the pH with glacial acetic acid instead of HCl, you won't introduce chloride ions.
Is CH2OHCH2OH a strong electrolyte?
No, CH2OHCH2OH is not a strong electrolyte because it is a covalent compound. Strong electrolytes dissociate completely into ions when dissolved in solution, while covalent compounds do not dissociate into ions.
What colors would you assume to be transmitted by a green solution?
A green solution typically transmits or allows the passage of green light. It absorbs other colors of light present in white light and reflects or transmits the green wavelengths, giving it a green appearance.
Why must a funnel be heated before hot acetanilide solution is heated and filtered?
Most likely so the glass will not crack as it expands as a result of being heated by a hot solution being poured into it.
When Dr. Farrell was a graduate student he once made up a pH 8.0 sodium acetate buffer. Why would the casual observer to this buffering faux pas come to the conclusion that he?
Not exactly sure what the question is asking, but sodium acetate will not buffer at pH 8. It is an ok buffer in the pH range of maybe 3-5 or so. Acetic acid is the weak acid of this buffer with a pKa near 10^-5. To make a decent buffer at pH 8, one needs a weak base, or a weak acid with a pKa closer to 8.
Assume that a solution forms the product mercury L acetate The product formed is what?
A+LS is "slightly soluble"
Assume that a soloution forms the product mercury i acetate the product formed is what?
When mercury(II) acetate is formed, it is typically produced by reacting mercury(II) oxide or mercury(II) chloride with acetic acid. The resulting compound is mercury(II) acetate, represented by the chemical formula Hg(C2H3O2)2. This product is a coordinate covalent compound where mercury is in the +2 oxidation state, coordinated with two acetate ions. Mercury(II) acetate is often used in organic synthesis and as a reagent in various chemical reactions.
How do you make 50mM ammonium acetate solution?
One mole of ammonium acetate is equal to 77.08g (this is the formula weight, FW, of ammonium acetate, which can be found on the side of the bottle). Another way of representing this is 77.08/mol (so, in one mole of ammonium acetate, there are 77.08grams of ammonium acetate).We have to use the FW value to calculate molarity (moles of solute per L of solvent).I am not sure what volume of the 50mM solution is desired, so I will assume that you need 1 L.50mM is equal to 50milli-moles of solute/1 L of solvent, which is the same as 0.05moles/L. This is what the math looks like:77.08g/mol ammonium acetate x 0.05mol/L = 3.854g/LSo, to make a 50mM solution of ammonium acetate in 1L of water, you will need to dissolve 3.854g of ammonium acetate into 1L of water.
Assume that a solution forms the product barium carbonate The product formed is?
Barium carbonate is formed when barium ions (Ba^2+) react with carbonate ions (CO3^2-) in solution. This reaction produces a white precipitate of barium carbonate, which is insoluble in water.
What is the molecular formula of copper acetate?
Copper ethanoate in solution consists of two parts: Ethanoate ion: CH3-(COO)- (to note this has a negative charge on the COO represented by the - and a bond after CH3 also represented by a -) This has only single bonds from both oxygens to the carbon, the charge is then spread across the two oxygens and the carbon making the molecule polar and soluble Copper ion: Cu2+ ions have a 2+ charge and so are in solution (generally anything with a charge will be in solution) When this is dehydrated the copper ethanoate is formed as a precipitate using 2 ethanoate ions and 1 copper ion to give a charge of 0 throughout the molecule. The formulae of this is Cu(CH3COO)2 and for some reason i cant get subscript and superscript to work on this so you will have to assume its there.

What does product in math terms?
I assume you're asking, "What does product mean..." It means the result of multiplication.
What is the most produced product in Wisconsin?
I would assume cheese.
How is the messengers of the gods?
I assume that the question is: Who is the messenger of the Gods? Hermes in Greek and Mercury in Roman.
Where does Mercury the god of travel live?
I'd assume on Olympus so he can quickly deliver messages.
Where to buy proactive solutions in abu dhabi?
please check the spelling of your product... i assume this is a product you are looking for. Proactiv Solutions....??
Is price a reflection of product quality?
Not at all. Consumers frequently see a product and assume the more expensive the better the quality of the product. Whilst there is, to a degree a fact to this, product price is no guarantee of good quality
