Question

HELP!! PLEASE out of these which one are acids and which ones are bases:

Ca/H20/NaCl/AgNO3/HCl/NaOH/Zn/HCl/CuSO4
NaCl/NH3/C5H12O/HC2H3O2/CuSO4/KI/Pb(NO3)2/NaHCO3 HELP!! PLEASE out of these which one are acids and which ones are bases:

Ca/H20/NaCl/AgNO3/HCl/NaOH/Zn/HCl/CuSO4
NaCl/NH3/C5H12O/HC2H3O2/CuSO4/KI/Pb(NO3)2/NaHCO3 @Chemistry

Answer 1

ACIDS give of hydrogens, and base takes hyrogens (another way to put it is acids takes the electron from the hydrogen giving away hydrogen as an H+ and base takes up that hydrogen giving the hydrogen its electrons to share) so using that concept which one do you think are bases and which are acids?

Answer 2

then for the ones that does not have hydrogen use the concept of bases donate the electrons while acids accept electrons

Answer 3

I am sorry Thanh,but that was confusing for me. Are you basically saying that all the ones with with H are acids and the ones without H are bases?

Answer 4

Nope. I am saying that compounds that accepts electrons are acidic and anything that donates electrons are basic. For example acids can give hydrogen off as H+ so it accepts the electrons from the hydrogen, and base can accepts H+ so it donates it electrons to the hydrogen

Answer 5

Here I'll give you one as to show my point. NaOH is basic because OH- accepts H+ from HCl (acidic) to yield NaCl and H2O

Answer 6

Oh wow, sorry that just made it more confusing...i am only in high school basic chemistry..i am not sure how you got HCl ,NaCl and H2O from NaOH

Answer 7

NaOH and HCl is what you wrote in your question or one of the few that you wrote in your question

HCl (acid) --> H+ and Cl- the chlorine takes up the electrons from the hydrogen so that it can be negative

NaOH (Base) --> Na+ and HO- the OH takes the electron from the Na

Base + Acid yields water

The hydrogen (H+) from the acid adds to the -OH from the base
The (H+) is positive charged it has no electrons so it wants electrons (electron acceptor)
The (-OH) is negative charged it has extra electrons so it wants to give away electrons (electron donator)

H+ reacts with -OH yields water which is H2O

Answer 8

:)! Thank you...that makes sense now! whew I thought i would never understand it...Thanks Thanh!:D

Answer 9

yep! anytime

Answer 10

Alison, Thanh is right on. But since you are in HS, let me get you started with the basics so you get it right every time. You will need to understand the main types of chemical reactions. What happens when Zn/Ca react with water?
What happens when something with -OH reacts with something like HCl.
WHat if some like that has neither OH or H, like NaNO3 reacts with CuCl2
and what happens when something burns in O2.
And you should just memorize the main strong acids and bases. (HCl, H2SO4, HNO3) and NaOH, KOH Ca(OH)2. Trust me. It will save your life.
