How do I calculate how much sodium hydroxide I need to …
WebSodium hydrosulfide, NaHS, is a highly alkaline liquid with a pH range of 11.5 to 12.5. The liquid solution is typically yellow to dark green in color and has a strong hydrogen sulfide (rotten egg) odor. Solutions of NaHS are considered stable in normal transportation. Solutions range from 20 to 45% strength by weight and weigh 9.6 to WebJan 9, 2008 · I have a situation where I'm using a 20% wt solution of NaOH. I need to provide 325 mol (13 kg) of NaOH (so 65kg of solution). The density I found for NaOH at 20% is … arataki

WebNaOH is miscible with water at all proportions but solidifies at 20°C if the concentration is higher than 52% (by weight), which can be considered the maximum water solubility at 20°C. NaOH has a very low vapour pressure (< 10-5 hPa at 25°C). The octanol water partition coefficient is not relevant for an inorganic substance such as NaOH. WebNaOH requirements for pH adjustments in the tank T4 include: 1. pH adjustment of the spent rinse water: (a) bed interstitial volume = volume of acid = 20% of the bed volume = 400 l; … WebMay 14, 2024 · Using a pH indicator strip will tell you that NaOH (sodium hydroxide) is a strong alkaline. This means it has a pH toward the top end of the pH scale, which ranges from 0 to 14. To calculate the exact pH, work out the molarity of the solution, then apply … There are many different ways of expressing the concentration of a given … If the ratio is not 1:1, use a modified version of the formula.
