What is the hydrogen ion concentration of a solution with pH = 8.75 ?

The answer is 1.778*10^-9

Explanation:

Using the formula

pH = -log[H^+]

Since the pH of the solution has been given to be 8.75,

Therefore,

8.75= -log [H^+]

Let's take H^+ to be x

8.75= -log x

Let's look for x, since the log is in base 10

X = 10^-8.75

X = 1.778 * 10^ -9

Therefore, H^+ =1.778 *10^-9

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³
