First dilute A.R. by pooring it SLOWLY into a large amount (10-fold) of (cold) water while mixing, and then (SO AFTER dilution) the same (molar) amount of NaOH (diluted) can be poored into it in the same way.
This careful procedure is required because of high reaction heat and aggressive chemicals and toxic fumes might escape when not done carefully.
Any acid can be used to neutralize a base such as sodium hydroxide. If you have a concentrated solution of sodium hydroxide, you could neutralize it most efficiently with a strong acid such as hydrochloric acid. You can also neutralize it with Coca Cola, or vinegar, or many other acidic chemicals, but it would require a larger amount than if you used hydrochloric acid.
The largest volume of 0.100M sodium hydroxide solution would be needed to neutralize a strong acid with a low molarity. This is because a lower molarity acid would require more moles of sodium hydroxide to neutralize it, resulting in a higher volume of the solution being needed.
To determine the percentage of sodium hydroxide in solid Drano, you can first dissolve a known mass of Drano in water and then titrate the solution with a standardized acid solution (e.g., hydrochloric acid). The amount of acid needed to neutralize the sodium hydroxide in the Drano solution can be used to calculate the percentage of sodium hydroxide in the original solid.
When just enough strong acid (e.g. HCl) is used to neutralize a strong base (NaOH), the pH should be neutral (pH = 7.0).
A solution of sodium hydroxide in water will have a pH close to 14, as sodium hydroxide is a strong base that dissociates completely in water to produce hydroxide ions, increasing the pH.

No, adding water to sodium hydroxide will not lower the pH. Sodium hydroxide is a strong base, and when dissolved in water, it dissociates to produce hydroxide ions, which make the solution more basic. To lower the pH of a sodium hydroxide solution, you would need to add an acid to neutralize the base.
No, adding solid sodium hydroxide to neutralize hydrochloric acid (HCl) would not cause sodium chloride to redissolve. The reaction between sodium hydroxide and hydrochloric acid forms water and sodium chloride, which remains in its dissolved form. The addition of solid sodium hydroxide would simply further neutralize the acid and increase the concentration of the resulting sodium chloride solution.
There are times when bacteria, acidify an infected site, therefore adding sodium hydroxide will neutralize the region for a basic site.
The largest volume of 0.100M sodium hydroxide solution would be needed to neutralize a strong acid with a low molarity. This is because a lower molarity acid would require more moles of sodium hydroxide to neutralize it, resulting in a higher volume of the solution being needed.
To effectively neutralize citric acid in a solution, you can add a base such as sodium bicarbonate or sodium hydroxide. The base will react with the citric acid to form water, carbon dioxide, and a salt, which will help balance the acidity of the solution.
Sodium hydroxide is not an unknown solution.
To determine the percentage of sodium hydroxide in solid Drano, you can first dissolve a known mass of Drano in water and then titrate the solution with a standardized acid solution (e.g., hydrochloric acid). The amount of acid needed to neutralize the sodium hydroxide in the Drano solution can be used to calculate the percentage of sodium hydroxide in the original solid.
You can calculate the concentration of a phosphoric acid solution by determining the volume of sodium hydroxide needed to neutralize it in a titration. The molarity of the sodium hydroxide solution and the balanced chemical equation for the reaction will allow you to find the moles of phosphoric acid present, hence the concentration.
