Ingestion of large amounts the phosphoric acid found in cola deserve to upset the body"s regulation of bone metabolism and reduce the absorption of calcium indigenous the diet. For this reason, world who are at hazard of developing osteoporosis are frequently advised no to drink lot cola.

You are watching: What is the molar concentration of h3o+ in a cola that has a ph of 2.670?



= 7.59*10^-4

Explanation:

Given:

pH of cola = 3.120

To determine:

The hydronium ion concentration,

Calculation:

The pH that a systems is a measure up of the concentration the the hydronium ion which consequently indicates the acidity of the provided solution.

*
" />

*
= 10^-pH" />

for the offered cola through pH = 3.120

*
= 10^-3.120=7.59*10^-4M" />



Answer : The hydronium ion concentration in an aqueous systems is,

Explanation : Given,

pH = 2.670

pH : the is identified as the an unfavorable logarithm that hydronium or hydrogen ion concentration.

Formula offered :

*
" />

Now placed the worth of pH in this formula, we get:

*
" />

*
=2.138 imes 10^-3M" />

Therefore, the hydronium ion concentration in an aqueous systems is,



The answer to your question is below

Explanation:

A.

= 2 x 10⁻¹⁴ M

pH = ?

Formula

pH = - log

Substitution

pH = - log <2 x 10⁻¹⁴>

Result

pH = 13.7

B.

= ?

pH = 3.12

Formula

pH = - log in

Substitution

3.12 = - log in

*
" />

Result

= 7.59 M



The pH of a systems is a measure up of the mountain of that solution. It relates come the hydrogen ion concentration existing in the equipment logarithmically. That is express as:pH = -log We calculation the hydrogen ion concentration as follows:pH = -log 2.670 = -log = 2.14x10^-3 M
