Question

The concentration of Hydrogen ion in a sample of soft drink is 4.0 x 10-3 M. What is its plH ? (log102 = 0.301) पेय पदार्थ के नमूने में हाइड्रोजन आयन की सान्द्रता 4.0 x 10 'M है । इसका pH क्या होगा ? (log102 = 0.301)​

Answer 1

Answer:

Solution



Verified by Toppr

Given: [H+]=3.8×10−3 M 

Needs to find: pH 

Formula to find: pH=−log10[H+]

Solution:  

We can put the values of H+ in above formula as,

pH=−log10[3.8×10−3]

pH=2.42

pH value of soft drink is 2.42.
