M is the [H] in a HC102 solution that has a pH of 3.78.
Explanation:
Given:
pH of the acid = 3.78
[H+] ion concentration = ?
The dissociation of the acid is shown as:
+
⇔ HClO2
however, weak acid like HClO2 does not dissociate or ionize completely which causes low hydrogen ion release in the solution.
pH is calculated by applying the formula:
pH = - log [H+]
To calculate the H+ ion concentration the equation will be expressed as:
[H+] = ![10^{-pH}](https://tex.z-dn.net/?f=10%5E%7B-pH%7D)
= ![10^{-3.78}](https://tex.z-dn.net/?f=10%5E%7B-3.78%7D)
= 1.6 X
M
The concentration or molarity of the Hydrogen ion in the solution of the acid is 1.6 X
M.
The difference betweek xylem and phloem is that (1) xylem is unidirectional it only moves up to the plants stem while phloem is bidirectional it goes uop and down to the stem and leaves. (2) Xylem only transport water and mineral to aerial part of the plants while phloem transports food and nutrients.
The correct answer is the Tyndall effect. This is also known as the Tyndall scattering. It is the light scattering by the particles in a colloid or in a suspension. This phenomenon is used to determine size and density of particles in colloidal matter.
