In bulk, it is most often handled as an aqueous solution, since solutions are cheaper and easier to handle. Simple theme. Caustic soda, or lye is sodium hydroxide.
But since nobody can quantify the problems for the environment you will in most cases get the answer: "In case of doubt it is better to dispose as toxic waste." If your drain is a little slow, you can often clean it out and speed it up by mixing 1/4 cup of citric acid and baking soda, pouring it down the drain, and then pouring boiling water over it. Normally I tend to learn these things the hard way, but life is too short to make all the bloopers oneself. Pour vinegar (weak acetic acid) into the drain. Everybody knows that small quantities make less problems for the environment. Why is 70% ethanol used for wiping microbiological working areas? I used a combination of chiseling and further breaking the puck into pieces to loosen the glass from (almost) all the pieces of sodium hydroxide. Of course, this was only part of the solution, and I had to chisel the brick off my hot plate with a kitchen knife and a hammer (notice the professionalism here).
Of course, as usual, the problem for us as backyard chemists is the availability, and (as usual) we could buy it. The pieces were then weighed.
You can stir it with a plastic or wooden spoon. It is an effective substance for use in unclogging drains and is often one of the active ingredients in commercially available drain cleaners. The reaction between the chemicals will produce bubbles. Change ), You are commenting using your Facebook account. When used in this way, it is crucial to follow safety precautions for 2 reasons: sodium hydroxide is extremely caustic and can cause severe burns, and the heat produced in this reaction could cause the solution to boil and splash back, which could cause burns and even blindness if it reaches your eyes. Why not 100% ethanol or methanol? Well the sodium hydroxide reacted with it very vigorously in the following equations: 2 Al + 6 H2O → 2 Al(OH)3 + 3 H2 It is true, the alkalinity of the formed sodium acetate is not harmful, so it had to be poured into drainage. One of the most famous reactions involving sodium hydroxide is saponification, a process that produces soap. After wiping up the excess liquids up with numerous paper towels, I wondered how I was going to get what was essentially a hockey puck of sodium hydroxide stuck to my hot plate to a usable form of the chemical. Yes, fats+lye makes soap. If the solution heats up, it may be sodium hydroxide. Under good conditions enough of the soap dissolves in the hot water to unclog the drain. Thankfully, there was no lasting damage to anything except my beaker. The. Soap, unlike fat, is water soluble and will rinse away with enough hot water. If you put some washing up gel into the NaOH solution, that will be a perfect household cleaning agent. These equations are actually how the drain cleaner destroys blockages in a pipe, but for me, this meant trouble. Eventually, I got the slab free from the hot plate.

This will create a volcano like effect, with a lot of bubbling and a lot of steam, but when it clears up, the water should go down your drain much quicker. By raising then cooling the temperature, the NaOH which is dissolved more than the water can hold will fall out of solution and turn into a paste at the bottom of the beaker, which you can retrieve.

Even one thing, you can use the keeping in air the open bottle for several days, when sodium hydrogen carbonate solution is formed with the carbonic acid content of the ir. Are there useful scientific drawing (include cartoon) programs to show my research work or review conclusion ? When triglycerides react with sodium hydroxide, they get converted into glycerol and a fatty acid salt, i.e. Anything I say should be taken as a suggestion, but not as a guarantee.
Remove the drain and pull away any hair or other matter that has become trapped. According to local regulations (Indirekteinleiterverordnung) there are maximum concentrations defined for several compounds, particularly for some heavy metal salts like mercury but also for copper.
Place your order today or contact a member of the team to discuss any technical queries you may have. This process is used in wet chemical fire extinguishers because it can change the burning oils or fats into non-combustible soap. The presence of sodium hydroxide, either as an ingredient in a cleaner or as a home-made aqueous solution, kick-starts saponification and converts these pesky fats into soaps. The heat helps melt greasy clogs. On the bottle its written that Assay = (35-38%), also weight per ml = (~1.18g). The clog was further down. Streptokinase.
Sodium hydroxide doesn't just melt the grease, it turns some of it into soap. Your … What is the Difference Between Propan-1-ol and Propan-2-ol? No explanation of how you remove them when the sink is filled with water that hot. The mechanism of how NaOH achieves this goes far beyond the simple fact that it is corrosive. Quickly, I took the beaker out of the garage and set it on a table to calm down. I have a steam wallpaper stripper about £30 to buy unless you know a decorator. Drawing software for scientific models (schemes). After the initial weighing, these big pieces were further crushed into semi-usable pieces. The only way you're going to get a huge clog like the one shown here is if you've got tons of fat in your drains, then pour too little drano/lye and then also don't thoroughly flush with hot water.
I want to calculate the colony forming unit of a bacterium which is frozen in glycerol solution. You can purchase sodium hydroxide (also called caustic soda) at any hardware supply store.

He named a relatively high price for unclogging the drain, but said that since we're friends of his, he'd make it cheaper. Second, it is a powder. When these two compounds react, one of the by-products is hydrogen gas.
Rinse it with water before screwing it back into place. Not only will this produce a caustic solution with a high pH, it will also release a lot of heat.
