Chemistry
1 answer:
Nina [5.8K]3 years ago
3 0

Answer:

5.555.

Explanation:

∵ pH = - log[H⁺],

<em>[H⁺] for weak acids = √Ka.C.</em>

Ka for CH₃COOH = 1.74 x 10⁻⁵, C = 0.16 M.

∴ [H⁺] = √Ka.C = √(1.74 x 10⁻⁵)(0.16 M) = 2.784 x 10⁻⁶ M.

∴ pH = - log[H⁺] = - log(2.784 x 10⁻⁶ M) = 5.555.

Acid strength in a series of h−a molecules increases with increasing size of
-BARSIC- [3]
Hello there!

The statement that Acid strength in a series of H-A molecules increases with increasing size of A is True.

When only the size is involved, increasing the size will increase the Acid strength because as size increases, the H-A bond will become weaker as the atoms will be farther apart. Acid strength is related to the ability to release H⁺ ions and a weaker H-A bond will release H⁺ more easily. 

Have a nice day!

Why is acid added to water during eletrolysis
DedPeter [7]

Answer:

Pure water is a non conductor of electricity and dilute acids in their aqueous solutions form free ions, which conducts electricity. Thus when we need to electrolyse water, a dilute acid is added to increase its conductivity.
