Question

7) What is the [H] of a solution that has a pH of 5.16?
a) 69 x 10 M b) 6.9 x 10 M
c) 0.69 % 10 M
d) all of these​

Answer 1

Answer:

For the numbers 1, 2, 3, 4, for example, we would have. Q1 = 1.5 ... extend to the lower and upper deciles (the 10th and 90th percentiles) rather than to the ... 1.44 With the outlier: x = 141.06 and M = 138.50.

Answer 2

The concentration of the hydrogen ion is $6.91 \times {10}^{ - 6}$.

Given:

The pH of a solution is 5.16

To find:

The concentration of the hydrogen ion.

Solution:

The relationship between pH and the concentration of the hydrogen ion in a solution can be given as-

$pH=-log[H^+]$

Given pH is 5.16.

Let the concentration of the hydrogen ion is x M.

So, we can write-

$5.16 = - log_{10}(x) \\ log_{10}(x) = - 5.16 \\ x = {10}^{ - 5.16} \\ x = 6.91 \times {10}^{ - 6}$

The concentration of the hydrogen ion is $6.91 \times {10}^{ - 6}$.
