HCl is a gas which is dissolved in water to form the solution the concentration expressed is very approximate so its not a primary standard.
HCl is not used as a primary standard
HCl, hydrochloric acid, is the primary standard used to titrate against potassium hydroxide.
ok, to make a secoundary color all you have to do is combine 2 different primarys such as blue and yellow, which makes green, a secoundary color.
Sodium hydoxide cannot be used as a primary standard because of its hygroscopic properties as a solid. Because it is so prone to absorbing water, it is impossible to accurately measure the mass of a solid sample, so instead it must be put into solution and tirated with a known acidic solution, such as HCl. This makes it a secondary standard as opposed to a primary standard. By. Kuatsienu Divine

HCl, hydrochloric acid, is the primary standard used to titrate against potassium hydroxide.
This answer should contain the amount of turns that the primary and secoundary have.
Basically primary producers are the plants an secondary producer are the animals who eat the plants like a rabbit or a catepillar.

sodium hydroxide is a secondary standard because it absorb the moisture from the air and its concentration will change
The usual primary standard for acid-base titration is sulfuric acid. Nitric acid tends to lose NO2 by volatilization and HCl is also more volatile.
The chemical formula (not symbol) of hydrogen chloride is HCl; for a diluted solution you can use "HCl dil." but this isn't a standard formula.
