What do they mean by the properties of acids and bases?

 

[pLuvia]

What the properties of acids and bases are.

Acids
- Sour taste
- Sting or burns skin
- In solution in conducts electricity
- Turns blue litmus red

Acid produces hydrogen ions, H⁺ when in solution

E.g
HCL ---> H⁺ + Cl^-
H₂SO₄ ---> 2H⁺ + SO₄^2-

Alkali (base)
- Soapy feel
- Bitter taste
- Good conductors of electricity when in solution
- Turns red litmus blue

Alkalis contains O^2- or a hydroxide OH^-

E.g
NaOH
Cu(OH)₂

Hope this helps

Bronsted-Lowry theory:

Acids donate protons (H+), and bases accept protons.

i think pLuvia nailed it there at this stage that is all you really need

 

[FroZenWaffleS]

ok lets say if we given a powder of an unknown weak base, how do we justify the properties??

 

[Riviet]

Add an acid in solution with it, to form a salt and H₂ gas, light a match and place it near solution for pop test.

 

[FroZenWaffleS]

What if the base was used in a titration??
How would you justify the assumed properties the base has?
It is a weak base and comes in a powder when solid and dissolves in water.

The base is most likely weak because the neutralisation is slightly acidic, and it is not neutral as Methyl Orange is used...

and don't copy that line >_>
