Vapor pressure : No data available Relative vapor density at 20 C : No data available Relative density : No data available Specific gravity / density : 1.18 g/ml Page 5 Sodium Hydroxide, 20% w/v Safety Data Sheet according to Federal Register / Vol. <>stream The density of 50% (w/w) Sodium hydroxide solution is 1.515 g/ml at 25C which means that the weight of the 1 ml of Sodium hydroxide solution is 1.515 g at 25C. 0000001254 00000 n The density of air at NTP is 1.205 kg/m3. endobj A second article will suggest applications of the same experiment that are suitable for experienced titrators. Since the aim is to test for the presence of the species in the analyte, they should not react with each other because this means changing their identities.The mixture of NaOH and NaHCO 3 is incompatible in such way that they cannot exist in the solution without occurrence of reaction that converts the reactants to Na 2CO3 and water. If you continue to use this site we will assume that you are happy with it. 2HCl + 2NaOH 2NaCl + 2H2O NaOH is insoluble in organic solvents and in a polar medium, it is soluble. WebSpecific Gravity: 1.5: Chemical Name or Material: Sodium hydroxide, 50 wt% solution in water: Show More Show Less: Documents Safety and Handling GHS P Statement Causes severe skin burns and eye damage. Recommended use and restrictions on use Use of the substance/mixture : For laboratory and manufacturing use % Woodworking Tools Clearance, xref ?ei}'ey+CQ ( k Q} ?^_}' Product name : Sodium Hydroxide, 40% w/w Product code : LC24120 1.2. At Mohawk College we store the dropper bottles containing the sodium hydroxide solution for long periods with no apparent ill effects. Some find significant digits so confusing that it might be easier to have students use 5.0 mL.
