An unknown solution has a ph of 8. how would you classify this solution?
acidic
there is not enough information to answer the question
neutral
basic

Answer : The correct option is, Basic.

Explanation :

pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.

The pH range is, 1 to 14.

When the value of pH is less than 7 then the solution is acidic.

When the value of pH is more than 7 then the solution is basic.

When the value of pH is equal to 7 then the solution is neutral.

As per question, an unknown solution has a pH of 8 that means the pH is more than 7. So, the solution will be basic in nature.

Hence, this solution is basic in nature.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
