Iodisation of salt is necessary because iodine deficiency lead to idiocy.
Salt is not a universal solvent. Water is often referred to as the universal solvent due to its ability to dissolve a wide variety of substances. Salt, on the other hand, is a solute that can dissolve in water or other solvents to form a solution.
The universal solvent is salt since it can dissolve a lot of solutes and salt does not have a pH category
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.
Universal indicators can be mixed with different substances. Universal indicators usually contain water, salt, propan-1-ol, sodium hydroxide, monosodium, phenolphthalein sodium salt, methyl red, bromothymol blue, and thymol blue monosodium salt
The ingestion of iodide prevents iodine deficiency. Worldwide, iodine deficiency affects about two billion people and is the leading preventable cause of mental retardation.[1] It also causes thyroidgland problems, including endemic goiter. In many countries, iodine deficiency is a major public health problem that can be cheaply addressed by iodisation of salt.
From wikipedia: A universal indicator is typically composed of water, methanol, propan-1-ol, phenolphthalein sodium salt, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt
red
do you mean solvent. because it is called universal solvent because it dissolves alot of different things
yes.water is a universal solvent
A salt solution with universal indicator will likely show a neutral pH, appearing green in color. This is because salts are typically pH-neutral compounds that do not significantly affect the acidity or alkalinity of a solution when dissolved in water.
Example of a soluble substance would be sugar and salt, both are easily soluble in the universal solvent, water
Sodium Chloride a.k.a. table salt or sea salt is neutral and so Universal Indicator will go Green with a Ph 7
