Question

1 true or false 1 point
solutions are formed when multiple pure substances mix chemically.
○ true
○ false

2 true or false 1 point
neutralization reactions are the only reactions that can produce water.
○ true
○ false

3 multiple choice 1 point
the ability for a solution to conduct electricity is due to...
○ the color of the solution.
○ the number of ions present in the solution.
○ the volume of the solution.
○ the mass of the solution.

Explanation:

Question 1

A solution is a homogeneous mixture formed by physical mixing (not chemical reaction) of solutes and solvents. So the statement is false.

Reactions like combustion (e.g., $2H_2 + O_2
ightarrow 2H_2O$) also produce water, not just neutralization. So the statement is false.

Electrical conductivity in solutions depends on mobile ions. Color, volume, or mass don't affect conductivity. So the correct factor is the number of ions.

Answer:

False
