NaOH is not particularly toxic but it is extremely corrosive. Depending on the route of entry, a lethal exposure could range upwards from a few milliliters. A person would notice the exposure immediately and attempt to wash it off because of the pain associated with the tissue destruction.

What happens when you add sodium hydroxide to lead?
Not a whole lot, actually. Sodium is much higher in the activity series than lead, so it doesn't react.
What Equipment do i need to make soap?
Soap is made by reacting an acid (for example sunflower and olive oils) with an alkali (for example sodium hydroxide). Sodium hydroxide being a much stronger alkali than sunflower oil is an acid, this reaction is done to weaken the alkali so it is not harmful to the skin. This reaction can be seen by dipping (for no more than a second) your fingers into a beaker of sodium hydroxide, the oil on your skin will react with the sodium hydroxide and a thin layer of soap will be formed on your fingers. This is safe to do, and does not hurt in anyway if you have only briefly dipped your fingers in. Some people add fragrances after this reaction has happened.
Why would you use a titration method when making potassium sodium and ammonium salts rather then just reacting the acid with large amounts of sodium hydroxide or something?
If you simply dump reactants together without careful measurements then you will have something left over. Say you want to make sodium nitrate by reacting sodium hydroxide with nitric acid. The two chemicals react in a 1:1 ration, meaning that one mole of sodium hydroxide reacts with one mole of nitric acid; no more, no less. If you simply dump a vat of nitric acid into a vat of sodium hydroxide you don't know how much of each substance you are mixing and chances are you will have more of one than the other. If there is more nitric acid than sodium hydroxide, then there will by nitric acid left over. You get a similar problem if you end up adding to much sodium hydroxide. The end result is that the product you want is contaminated by an excess of one reactant and you have wasted chemicals. If you titrate you will be able to mix together your reactants in exactly the right amounts (within a small margin of error) so that the end product is as pure as you can make it and you waste as little of your reactants as you can.
How much sodium should an active person get a day?
Maybe like 100 sodium maximum.
What will happen when aluminum oxide is mixed with Sodium Hydroxide?
Not very much unless it is also mixed with water and subjected to high temperature and pressure to prevent the water boiling. This reaction is used as part of a method for extracting aluminum from bauxite ore. At normal temperatures and pressures, aluminum oxide will dissolve slowly in sodium hydroxide solution to form various complex sodium aluminum hydroxides.
How much sodium hydroxide in grams must be added to seawater to completely precipitate 86.9mg of magnesium?
how much sodium hydroxide in grams must be added to seawater to precipitate 86.9mg of magnesium present?
What is one way sodium chloride and soap are alike?
Both contain the element sodium. Ohter than that there is not much similarities. soap is generally sodium hydroxide.
Sodium is preferred over potassium in industrial applications because why?
$$$$$$ Sodium is cheaper!!!!$$$$$$ They both work great for the same purposes and are very often interchangeable. (But potassium hydroxide makes much softer and, to me, more pleasant feeling soap than sodium hydroxide)
How much heat is released when 200 grams of sodium hydroxide dissolve in water?
-222.55 or -223
How do you you determine the percentage of sodium hydroxide in solid Drano?
See how much it takes to pass out when ingested orally.
What happens when you add sodium hydroxide to lead?
Not a whole lot, actually. Sodium is much higher in the activity series than lead, so it doesn't react.
How much does 25 percent sodium hydroxide weigh per gallon?
Just about 10.68 pounds per gallon.
What is the pH number of sodium hydroxide?
Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.
How much sodium hydroxide has to be added to acid to form a neutral solution?
i dunno i think, 1st of all, record the pH of the soln concerned. To my opinion, sodium hydroxide is an alkali, thus, its pH is/should b more than 7. Addition of sodium hydroxide to neutralise a soln should b dne to an acidic soln, that is, pH less than 7. By mixing sodium hydroxide to an acidic soln, the pH wil bcme automatically 7 n thus wil b neutral..
What happens to the metal elements in leaves when they are burned?
Potassium hydroxide, sodium hydroxide, magnesium hydroxide, iron oxide, also various other oxides and hydroxides and maybe even a little cyanide based salts(not very much).
What is the systematic name of lye?
Lye is one of those "common names" that, particularly when combined with adjectives, might mean a couple of different compounds. The canonical lye is sodium hydroxide. However, potassium hydroxide has very similar chemical properties, and I've seen terms like "wood lye" that indicate it's actually the potassium compound instead. "Caustic lye" is a new one on me; both compounds have common names that include the word caustic (caustic soda for sodium hydroxide, caustic potash for potassium hydroxide), so it might be either one. If it's in a recipe for soap or something, it doesn't really matter all that much; as stated earlier, they have very similar properties and either will work.
What happens when you mix sodium hydroxide and sodium chloride?
Sodium chloride is dissolved in water and dissociated in ions.
