What is the ph of a solution with a concentration of 4.2 × 10–5 m h3o+?

2.31
4.38
5.62
6.87

Answer : The correct option is, 4.38

Explanation : Given,

concentration of =

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

Formula used :

Therefore, the pH of a solution is, 4.38

c u c l 2 + 2 n a n o 3 → c u ( n o 3 ) 2 + 2 n a c l

  long weird answer but i hope this works
