What is the difference in concentration between a pH of 7 and 12?

Ratling [72]

Answer:

The pH of a solution is simply a measure of the concentration of hydrogen ions,

, which you'll often see referred to as hydronium cations,

More specifically, the pH of the solution is calculated using the negative log base

of the concentration of the hydronium cations.

Now, we use the negative log base

because the concentration of hydronium cations is usually significantly smaller than

As you know, every increase in the value of a log function corresponds to one order of magnitude.

Which of the following statements about alkenes is not correct?

professor190 [17]

<span>Option-C: They react mainly by substitution.

Explanation:
Alkene doesn't give substitution reactions because they are non polar in nature. The double bond in alkene is responsible for Electrophillic Addition reactions as it electron rich and nucleophilic in nature. Reaction of Alkene is given below,</span>
