5 mL of NaOH
Sodium hydroxide in a pure form is a solid, so you cannot dissolve anything in it. Normally, NaOH is used as an aqueous solution. But salicylic acid dissolves in water, so the presence of NaOH in the water is irrelevant to the solubility of salicylic acid. It is the water, not the NaOH, that dissolves the salicylic acid.
Alcohols react with NaOH, as ethanol forms sodium ethoxide with NaOH.
Methyl orange
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
Methoxyphenol is a phenol derivative and so, is soluble in water. This means that methoxyphenol will dissolve in an aqueous NaOH solution, but will not react with the NaOH.

Methyl orange shows yellow color in an NaOH solution.

This is methyl formate an ester it does not react with Na but hydrolysed into methyl alcohol and formic acid with aqueous NaOH

Any reaction occur.
The mass of lead(II) nitrate required to react with 370 g NaOH is 1 531,9 g.
Na + 2H2O -----> H2 + NaOH If you have 2.5 moles water you need 1.25 mol elemental sodium
