why does NaCl dissolve completely in 6% HCL?
Q. NaCl is a neutral salt, so is this a reaction or is it just an NaCl + HCl = dissolves kind of thing?
Asked by lola-exis - Sat Jan 30 16:35:00 2010 - - 2 Answers - 0 Comments

A. It's simple, yet also a little complicated. I don't know what your level of chemistry is, so I hope I don't go too indepth. 6% HCl is called an aqueous solution, meaning it is mostly water. It is 6% HCl, but also 94% water. NaCl is an ionic compound, meaning the two atoms are held together because of a charge difference, Na+ and Cl-. Water dissolves ionic compounds because the water molecules form something called hydration shells around charged ions. Water itself is a polar molecule (it has a dipole) due to its bent shape. One end has a slight negative charge, the other end has a slight positive charge. The attraction between the negative pole of water and the positive Na+ ion is greater than the attraction between Na+ and Cl-, so… [cont.]

Name for a lab involving how to produce NaCl by taking NaHCO3 and HCl and heating the two?
Q. I need to do a FORMAL lab report on a lab where we took Sodium Bicarbonate (NaHCO3(s)) and Hydrochloric Acid (HCl(aq)) and heated the two to make Table Salt (NaCl). I can't think of a good, scientific name for it that doesn't start with "how". My teacher never said we can't use how, but I think that this is a lab report, not a how-to guide. THANKS!

A. NaOH and NaCl are ionic compounds and water soluble. So they will dissociate in water to yield negative and positive ions. As movable ions conduct electricity, they conduct electricity. HCl , when dissolved in water, dissociate into H+ and Cl- ions. So in solution, it will also conduct elctricity

Why is a mixture of HCl and NaCl function poorly as a buffer?
Q. Is it because they are salts?
Asked by honey(*_*) - Mon Apr 2 18:04:35 2007 - - 2 Answers - 0 Comments

A. It's because HCl is a strong acid, and 100% ionised in solution. The acid used in a buffer has to be a weak acid.

A. Is the answer C? The number of moles for both H_2_SO_4 and 2NaCl are the same so you can use either to calculate the grams of HCl produced. 4moles NaCl [(2moles HCl / 4moles NaCl)] * (36.15g HCl / mol HCl) Hope its right, I got 144.6g which is close enough (I rounded)

A. add baking soda NaHCO3 to all 3 only the one with HCl will react and bubble be careful use a little and wear proper lab gear. then add a solution of HCl to the other two the one that increases in temperature is NaOH solution and that how to do it with out indicator otherwise use litmus red and blue the HCl will turn the blue to red The NaOH will turn the red to blue and the NaCl will have little to no effect on either color

A. When you write the equation out, your products are the things in the second half of the equation. So the products here are NaCl and H2O. -- If it asks you for the reagents, it's the first half.

Asked by scs0077 - Thu Apr 23 16:30:06 2009 - - 4 Answers - 0 Comments

A. Since the Na compound is ionic you have Na+ and HCO3- the HCO3- will act like a weak base in and accept the proton from the HCl now the Na+ and Cl- will pair up and the HCO3- will pair up with the H+ The H2CO3 is your conj. acid since HCO3- is the conjugate base in each reaction such as this you *always* have conj. acid/base pairs.

Asked by Jaymie - Thu Jan 10 14:12:30 2008 - - 3 Answers - 0 Comments

A. In almost all types of these mass in/mass out problems, you have to convert to MOLES. So if you take 132 g of NaCl and divide by its mole wt, you get the number of moles of HCl. Now you need your reaction: ...NaCl + H2SO4 -> NaHSO4 + HCl which tells you that 1 mole of NaCl gives 1 mole HCl. So you can determine the moles of HCl you get from your NaCl weight. Then convert that to mass by multiplying the moles by the mole wt of HCl.

A. NaCl will not react with HCl, they are both already chlorides. NaCl is always NaCl, NaCl2 does not exist. H is always H2, hydrogen is diatomic. Under extremely high pressure you could get sodium hydride and Cl2, but NaH does not last.
