Carbonated cola is an ext acidic 보다 coffee or even orange juice because cola has phosphoric acid. What is the molar concentration the in a cola that has a ph of 3.120? (for with far-ranging figures, see hint 3.) view accessible hint(s) what is the molar concentration that in a cola that has actually a ph that 3.120? (for with significant figures, view hint 3.) 7.58 × 10−4 7.59 × 10−4 7.6 × 10−4 3.120 × 10−3 0.494 1.318 × 103


Answer;

= 7.59 × 10^-4 M

Explanation;

The molar concentration that in a cola through a pH that 3.120 deserve to be calculated by:


=10−pH

=10−3.120

=7.59×10−4M

Ingestion of big amounts the phosphoric acid discovered in cola have the right to upset the body"s regulation the bone metabolism and also reduce the absorption of calcium from the diet. For this reason, people who room at threat of occurring osteoporosis are often advised not to drink much cola.

Explanation:

Given:

pH that cola = 3.120

To determine:

The hydronium ion concentration,

Calculation:

The pH the a equipment is a measure of the concentration that the hydronium ion which subsequently indicates the acidity of the offered solution.

for the given cola v pH = 3.120

= 10^-3.120=7.59*10^-4M" title="ed1df">


Answer : The hydronium ion concentration in one aqueous equipment is,

Explanation : Given,

pH = 2.670

pH : the is defined as the an adverse logarithm the hydronium or hydrogen ion concentration.

Formula supplied :

" title="841e8">

Now put the worth of pH in this formula, us get:

*
" title="c63af">

*
=2.138times 10^-3M" title="2b565">

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


pH = ?

Formula

pH = - log in

Substitution

pH = - log in <2 x 10⁻¹⁴>

Result

pH = 13.7

B.

= ?

pH = 3.12

Formula

pH = - log in

Substitution

3.12 = - log in

The pH that a systems is a measure of the mountain of that solution. It relates come the hydrogen ion concentration current in the equipment logarithmically. It is to express as:

pH = -log

We calculate the hydrogen ion concentration as follows:

pH = -log 2.670 = -log = 2.14x10^-3 M
