Answer: True

Explanation:

Using the pH scale, that ranges from 0 - 14.

Acidic Substance are within the range of 0 - 6.9

Neutral substance ( e. g water) is assigned 7,while an Alkaline (Base) substance is within the range of 7.1 - 14.

False

if the pH is 8, this is basic because based on the pH scale, any below 7 is acidic, above 7 is basic and at 7 is neutral.

Calculate the adjusted retention times for both pentafluorobenzene and benzene if the elution time for unretained solute is 1.06
vovangra [49]

Answer:

Pentafluorobenzene: 11,92 min

Benzene: 12,14 min

Explanation:

<em>Retention time of pentafluorobenzene is 12,98 min and 13,20 min of benzene.</em>

The adjusted retention time is the time an analyte spends in the column not the stationary phase. As time of unretained solute is 1,06 min the adjusted retention time for an analyte is:

tr' = tr - 1,06min

For pentafluorobenzene:

tr' = 12,98min - 1,06min = <em>11,92 min</em>

For benzene:

tr' = 13,20 - 1,06min = <em>12,14 min</em>

<em></em>

I hope it helps!

PLEASE HELP ME The pH scale for acids and bases ranges from _____.
inysia [295]

The pH scale for acids and bases ranges from 1 - 14. The answer is letter C. The rest of the choices do not answered the question above. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14. From here we can derive the values of each concentration.

 


 -log[H+ ] + -log[OH- ] = -log[10-14]


pH + pOH = 14


So pH = 14 – pOH and pOH = 14 –

pH 


It would be B.
