If the solution is brilliant re in alkalies and decolorized
by acids it’s the time to used phenolphthalein in analysis as an indicator. The
resulting solution is acidic, so you need an indicator that has a pH range that
includes pH values below 7.0, like methyl orange, methyl yellow If titrating a
strong acid and a weak base and it’s time to use as an indicator called bromophenol
blue .
A strong electrolyte like MgCl2 dissociates completely as per the following reaction:
![MgCl_2 ----\ \textgreater \ Mg^{2+} + 2Cl^-](https://tex.z-dn.net/?f=MgCl_2%20----%5C%20%5Ctextgreater%20%5C%20%20%20Mg%5E%7B2%2B%7D%20%2B%202Cl%5E-)
As you can see, from 1 molecule of MgCl2 produces 3 ions on dissociation.
So, 1 mole of MgCl2 produces 3 moles of ions.
Now, Moles of MgCl2 = Volume x Molarity
= 0.04 x 0.345 [Change volume to Litres]
= 0.0138 moles
Now, total moles of ions = 0.0138 x 3 = 0.0414

Hey mate....
Explanation:
This is ur answer....
<em>Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Starch is stored in seeds and other plant parts as a food source.</em>

Answer:
Milk is essentially a colloidal dispersion of fat in water. ... However, the fact remains that the fat and water components cannot be mixed together from a solution. There are therefore, two distinct immiscible liquid phase's present, which is why it is a heterogeneous mixture.
<span>Scientific notation is used to express large numbers in a way that is to use, readable, comparable to other numbers and convenient. It is especially useful for things that are very large and very small because it is very tedious to work with many zero's when completing complex math problems.</span>
