What is the difference between pH and pOH?
natali 33 [55]

Answer:

pH measures ratio of H+ ions to OH- ions of substances

pOH measures ratio of OH- ions to H+ ions of substances

Explanation:

pH is a scale which measures the ratio of H+ ions to OH- ions to identify how acidic or basic a substance is. This is because acidic substances have high amounts of H+ ions and low amounts of OH- ions, and therefore have a higher ratio of H+ to OH- ions. (And vice versa for bases, low H+ to OH- ratio) On a pH scale, acidic substances have a pH of 0 to 7, water (neutral pH, not acidic nor basic) has a pH of 7, and bases have a pH of 7-14.

pOH is very similar to pH but measures the opposite: the ratio of OH- ions (indicative of a base) to H+ ions (indicative of an acid). Therefore the pH values are reversed on the scale: Basic substances have pOHs below 7, and acidic substances are above 7 on the pOH scale.

Fundamentally, these two scales measure the same thing is the same way, one just measures the ratio one way (H+:OH-), while the other measured them the other way (OH-:H+), resulting in flipped values on the scales:

pH: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14

      <---Acidic--->   <------Basic------->

pOH: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14

         <----Basic---->  <-----Acidic------->

Hope this helped!

Nitrogen is used to keep food frozen during transportation.
Greeley [361]

Answer:

Gaseous nitrogen has unique chemical and physical properties that make it suitable for use in food processing. Nitrogen is inert which means it will not react with prepared food materials, which can alter their aromas or flavors. Also, gaseous nitrogen will effectively displace oxygen minimizing oxidation and the growth of microorganisms that cause foods to lose their freshness and deteriorate faster.
