Dissolve approximately 0.25g of Borax in distilled water. Titrate against hydrochloric acid using methyl orange indicator. At end-point, solution should be almost colourless against a white background.
disadvantage: it has a pungent smell
There are multiple advantages to using ethanoic acid as a descaler. It is a weak acid, it does not damage most surfaces, does not bind to metals and is cheap and common. Most people would know it as vinegar.
You can try using ethanoic acid (vinegar) instead. It is much safer and more easily obtainable, although is is a weaker acid. But the characteristic vinegar smell is likely to give you away so if you are performing a close up project then it is not recommended. Another alternative is to use citric acid. Aqueous citric acid looks like hydrochloric acid (both colourless) and does not have that smell. You can buy that in baking shops.
A universal indicator is an indicator that changes color along with changes in pH level. The purpose of using it is to find a point at which a mixture of acid and base becomes neutral.
Ethanoic anhydride cannot be dehydrated any further as it is already the dehydrated form of Ethanoic acid. You can remove water from Ethanoic acid by using Concentrated H2SO4.

Yes, the indicator react with the solution.
by using hydrogen atoms

Color marking is the act of using different colors to distinguish or identify motifs or patterns in a poem.
The question mark will distinguish a question from a sentence. How will you distinguish yourself in class today? People who are "color blind" cannot distinguish the color red from green.
