Ingestion: Can burn the lips, tongue, throat and stomach. Symptoms may include nausea, vomiting, stomach cramps and diarrhea. Can cause death. Effects of Long-Term (Chronic) Exposure: Conclusions cannot be drawn from the limited studies available. Can cause dry, red, cracked skin (dermatitis) following skin contact.
For a 50% 50 % sodium hydroxide solution, a typical MSDS looks like this and states: Skin Contact: In case of contact, immediately flush skin with plenty of water for at least 15 15 minutes while removing contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used. Wash clothing before reuse.
Range for sinkable Acids/Bases is between 5.5 and 12 (has to do with the piping, so that may vary a bit depending on the city). So if you're in that range, you're fine to drain it. Depends where you are and what waste water permits you have. At my company, pouring any chemical solutions down the drain is forbidden.
Best Answer. The best way is to mix it with Hydrogen Chloride (HCl). This acid will react with Sodium Hydroxide (NaOH), which is a base, and the end product will be water (H2O) and table salt ...
You can find lots of good sources of free MSDSs online through Google. Just google "Hydrochloric acid MSDS". I would look for one that appears to come from a reputable source, such as a commercial supplier. As an example, I have linked the MSDS for concentrated HCl from Fisher Scientific. Section 7 of this MSDS is titled "Handling and Storage".
A newer label put on top says "sodium hydroxide". It is brown, and when dissolved in water makes a brown solution with some residual brown grains at the bottom. The solution has a very high pH as one would expect from sodium hydroxide. I saw an MSDS online that says it does not contain asbestos, despite being called "soda asbestos". So what is it?
According to the MSDS HCl is a Liquid. It is also found dissolved in water. The state symbol for sodium hydroxide is (s), indicating that it is in solid form. It is H2SO4. Apart from this an (aq ...
As to the question at hand, the reaction of sodium bicarbonate with sodium hydroxide would produce water and sodium carbonate as pointed out by commenter Poutnik. While sodium carbonate is a weaker base compared to sodium hydroxide (pKa of sodium carbonate is 10.33 compared to 15.7 for sodium hydroxide, according to Wikipedia) it is still basic ...
Most D-1 materials will also cause longer term effects as well (those effects that are not noticed for months or years). Examples of some D-1 materials include carbon monoxide, sodium cyanide, sulphuric acid, toluene-2,4-diisocyanate (TDI), and acrylonitrile. The symbol for Class D - Division 1 (D-1) is a skull and crossed bones inside a circle.
I tried reacting copper sulfate with sodium hydroxide to get copper hydroxide, which should precipitate, according to the following equation: $$\ce{2NaOH + CuSO4 -> Cu(OH)2(s) + Na2SO4}$$ I looked on Google Images, and the color of copper hydroxide is light-blue, but something interesting happened when I mixed these two solutions: the ...
