What is the boiling point of water at an elevation of 1.55×104 ft ?
horsena [70]
The computation for this problem is:
(1.55x10^4 / 1.0x10^3) x 19.8 mm Hg
= 15.5 x 19.88 mm Hg
= 308.14 mm Hg decrease 
= 308.14 x 0.05 C = 15.407 deg C 
deduct this amount to 100
100 – 15.407 = 84.593 C 
ANSWER: 85 deg C (rounded to 2 significant figures)

A substance with a high [H ] would likely have which additional characteristics? a high [OHâ€"" ] and a high pOH a low [OHââ
viktelen [127]

The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.

The substance having high \rm [H] will have:

Option B. A low \rm [OH ^{-}] and a high \rm pOH

This characteristic can be explained as:

  • The concentrations of \rm [H^{+}] and \rm [OH ^{-}] are inversely dependent on each other so when the concentration of  raises then the concentration of \rm [OH ^{-}] drops and vice versa.

  • The pH of a solution or substance is calculated with the help of:

\rm  pH  = \rm - log  \rm [H^{+}]

From the formula, it can be deduced that when the concentration of \rm [H^{+}] is high then the pH has a low value and it means that the solution is acidic.

  • pH can also be written as:

\rm pH + pOH &= 14 \\\\\rm pOH &= 14 - pH

From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.

Therefore, when pOH is in high concentration then \rm [OH ^{-}] is low.
