Question

21.A). Fill in the blanks
(1x51
1). When a metallic oxide dissolved in water, the solution formed has a high concentration of
ions (H", H30*,OH)
ii). Higher the ph value of a solution, the more
(alkaline , acidic)
iii). Conversion of ethene to ethane is an example of (hydration, hydrogenation)
iv). The basicity of acetic acid is
(1,3,4)
v). across a period, the ionization potential
(increase, decrease)​

Answer 1

Explanation:

1) hydroxide ions OH

2) alkaline

3) Hydrogenation

4) 1

5) The ionization energy of an element increases as one moves across a period in the periodic table because the electrons are held tighter by the higher effective nuclear charge.

Answer 2

Answer:

1) OH

2) Acidic

3) Hydrogenation

4) 1

5) Increase
