Answer:
1. Both
2. Acid
3. Acid
4. Base
5. Acid
6. Neither
7. Neither
8. Base
9. Acid
Explanation:
In Chemistry, a chemical compound can be either a base or an acid.
An acid reacts with metals to produce bubbles of hydrogen gas and it also reacts with carbonates while a base feels slimy to the touch. They both can change the color of a litmus paper.
Base has a sour taste while acids have a bitter taste (please do not use this characteristic to test for an acid in the laboratory)

Answer:
The molarity is 0.203 M
Explanation:
Using the formula C(oxi) x V(oxi) / [C(red) x V(red)] = N(oxi) / N(red)
Where oxi and red means reducing agent and oxidising agent respectively.
C = Concentration, V = Volume and N = number of moles.
C(oxi) = 0.5 M
V(oxi) = mL
C(red) = ?
V(red) = 30mL
Equation of reaction = 2K2S2O3 + KI3 = K2S4O6 + 3KI
so N(red) = 1 , N(oxi) = 2
from the equation above,
C(red) = 0.5 x 25 x 1 / (2 x 30)
= 0.203 M.
