which of the following oxides will give the most basic solution when dissolved in water?
a) so2
b) co2
c) k2o
d) p4o10
e) so3
i know that the answer is c but can you explain how to solve this problem?

The correct answer is Option C.

Explanation:

Oxides are formed when a metal or a non-metal reacts with oxygen molecule. There are two types of oxides which are formed: Acidic oxides and basic oxides.

Acidic oxides are formed by the non-metals.

Basic oxides are formed by the metals.

From the given options:

Sulfur is the 16th element belonging to Group 16 and period 3 of the periodic table. This is a non-metal and will form acidic oxide.

Carbon is the 6th element belonging to Group 14 and period 2 of the periodic table. This is a non-metal and will form acidic oxide.

Potassium is the 19th element belonging to Group 1 and period 4 of the periodic table. This is a metal and will form basic oxide.

Phosphorus is the 15th element belonging to Group 15 and period 3 of the periodic table. This is a non-metal and will form acidic oxide.

Sulfur is the 16th element belonging to Group 16 and period 3 of the periodic table. This is a non-metal and will form acidic oxide.

Hence, the correct answer is Option C.

the answer is b & c i believe : )
