Asolution with a hydrogen ion concentration [h+] of 1.0 x 10-4 m is more acidic than a solution with a [h+] of 1.0 x 10-9 m.
true
false

True.

Explanation:

We can calculate the pH of the solution using the relation: pH = - log[H⁺].

pH is a logarithmic scale used to specify the acidity or basicity of an aqueous solution.

pH (0-7) is the acidic region and (7-14) is the basic region.

As the value of pH is lower means highly acidic solutions.

pH = - log[H⁺] = - log(1.0 x 10⁻⁴) = 4.0.

If we calculate pH directly, we will found that the pH of this acid is 9 and this is not accepted.

Actually, it is very diluted acid that has a pH of 7.0 because there is another source of [H⁺] from water that has a concentration of (1.0 x 10⁻⁷).

So, the concentration of [H⁺] is (1.01 x 10⁻⁷).

∴ pH = - log[H⁺] = - log(1.01 x 10⁻⁷) = 6.995.

It is clear that A solution with a hydrogen ion concentration [H+] of 1.0 x 10⁻⁴ M is more acidic than a solution with a [H+] of 1.0 x 10⁻⁹ M.

So, this statement is true.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
