If the hydrogen ion concentration of an unknown solution is 4.56E-7, what is its pH and will this form an acid or a base?
Inessa05 [86]

If the hydrogen ion concentration of an unknown solution is 4.56E-7, the pH of the solution will be 6.34 and it will form an acid.

<h3>How to calculate pH from H+?</h3>

The pH, which is the power of hydrogen, can be calculated from the hydrogen ion concentration using the following expression:

pH = - log [H+]

According to this question, the hydrogen ion concentration of an unknown solution is 4.56E-7. The pH is as follows:

pH = - log [4.56E-7]

pH = 6.34

Therefore, If the hydrogen ion concentration of an unknown solution is 4.56E-7, the pH of the solution will be 6.34 and it will form an acid.

What are the two variables that affect the electric force between two objects?
givi [52]

Explanation:

The electrical force between two objects is given by the formula as follows :

F=\dfrac{kq_1q_2}{d^2}

k is electrostatic constant

q₁ and q₂ are electric charges

d is distance between charges

So, the two force between two charged objects depends on the product of charges and distance between charges.
