Question

the concentration of H+ ion in a sample of soft drink is 3.8*10^-3M.what is it's pH?

Answer 1

• GIVEN: pH=3.8×10-³
• TO FIND pH OF SOFT DRINK SAMPLE

pH= -㏒[H+]

   = -㏒3.8×10-³                      

   = -㏒3.8 - ㏒10-³                 ( ㏒3.8=0.58 )

   = -0.53 + 3

   = 2.42            

   pH of soft drink sample =2.42

Answer 2

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\purple{R}}}}$

❤..pH= -${log[3.8×10^-3]}$

= _ ${{log[3.8]+log[10^-3]}}$

_ ${{(0.58)+(-3.0)} = -{_2.42} =2.42}$

Therefore, the PH of the soft drink is2.42 and it can be inferred that is acidic
