6 - one sodium atom, 1 hydrogen atom, 1 carbon atom, and 3 oxygen atoms.
Single displacement and combustion reactions are ALWAYS redox.
Answer:
Formic acid, citric acid, Oxalic acid, washing soda, baking soda, etc. can be some examples of natural acids and natural bases. They both have domestic, industrial, and various other purposes.
Explanation:
<h3><u>
NATURAL ACIDS</u>
:</h3>
There are lots of natural acids present in our nature. Some of them are the following:
> <u>Formic acid</u>
USE: It is used in the stimulation of oil and gas wells as it is less reactive towards the metal.
> <u>Citric acid</u>
USE: It is considered as the best rust remover as it doesn't harm the metal just remove the rust.
> <u>Oxalic acid</u>
USE: It easily remove iron and ink stains and that's why it is used as an acid rinsing material in Laundries.
<h3><u>
NATURAL BASES</u>
:</h3>
There is a variety of natural base found in our nature which founds a lot of uses in day to day life. some of them are the following:
> <u>Washing soda</u>
USE: It is used in commercial detergent mixture to treat hard water.
> <u>Baking soda</u>
USE: It is the best rising agent used mostly in cooking and for domestic purposes like removing stains, etc..
Some of the solutions exhibit colligative properties. These properties depend on the amount of
solute dissolved in a solvent. These properties include freezing point depression, boiling
point elevation, osmotic pressure and vapor pressure lowering. From the given choices, the correct answer is the first option. Pure water will have the lowest boiling point because there are no solute particles to change the boiling point of water while other options will have an elevated boiling point because of the solute.
