What is the concentration of H+ ions at a pH = 7? mol/L What is the concentration of OH– ions at a pH = 7? mol/L What is the rat
AnnZ [28]
<h3><u>Answer;</u></h3>

= 0.0000001 mol/L  

= 0.0000001 mol/L  

= 1:1

<h3><u>Explanation;</u></h3>

What is the concentration of H+ ions at a pH = 7?

The formula for ph is given by:

pH=−log10[H+]

In calculating for the concentration of hydrogen ion, the formula is given by:

[H+]=(10)^(-pH)

Therefore; at pH = 7

[H+]=(10)^(-7)

<u>= 0.0000001 mol/L </u> 

What is the concentration of OH– ions at a pH = 7?

pH+pOH=14

7+pOH=14

pOH= 7

[OH-]=(10)^(-pOH)

[OH-]=(10)^(-7)

<u>= 0.0000001 mol/L  </u>

What is the ratio of H+ ions to OH– ions at a pH = 7?  

1:1

Find the product of 30−−√ and 610−−√. Express it in standard form (i.
Helen [10]
The product of √30 and √610 is 10√183.


√30  = √(2×3×5)
and √610 = √(2×5×61

Since 61 can't be factorised further.
Therefore, the value of √30×√610 is
= √(2×3×5×2×5×61)
= 2×5×√(3×61)
=10√183
