sodium thiosulfate pentahydrate melting point
Category : Uncategorized
When all of the substance changes to liquid, its temperature begins rising again thanks to supplying heat. If you want to accelerate the measurement, it is possible to intensify the heating of the pentahydrate, or you can place the container nearer to the flame. Sodium thiosulfate pentahydrate is a white crystalline substance with a melting point between 48 °C and 49 °C) which makes it ideal for this experiment. There is a danger of burning! However, there is a risk that the temperature stabilization will not be as distinctive, or the middle part of the graph will be much shorter. This experiment typically takes a relatively large part of a lesson (e.g. The melting point generally depends also on the pressure and is affected by additives – e.g. The temperature at which a crystalline substance changes its state to liquid is called a melting point tm. Chemsrc provides sodium thiosulfate pentahydrate(CAS#:10102-17-7) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Pour about 20 grams of sodium thiosulfate pentahydrate in a glass container (tube). However, during this experiment, you can attend to other activities – instruction, examination etc. Show More. Journals | Articles of sodium thiosulfate pentahydrate are included as well. check more sodium thiosulfate pentahydrate price, Home | This is one of the basic physical characteristics of crystalline substances – amorphous substances change to liquid state by gradually decreasing their viscosity.

Articles of sodium thiosulfate pentahydrate … one half). The container, however, is heated by the same heat input. Do not touch the container or the stand right after the measurement. Incompatible with strong acids, iodine, mercury. 1. Stop the measurement after the temperature of the sodium thiosulfate pentahydrate exceeds 60 °C. If you use an alcohol burner or a propan-butan burner, make sure that there is enough fuel for 25 minutes burning before starting the measurement. It is soluble in water. Tools and equipment usually found at schools, Change in Internal Energy by Performing Work: Nail Hammering, Conversion of Kinetic Energy into Internal Energy: Blow with a Mallet, Conversion of Kinetic Energy to Internal Energy: Falling Weight, Experimental determination of Specific Heat of Water, Comparing Specific Heat of Water and Vegetable Oil. The substance is not subject to any P-statements or H-statements. Choose required ranks and required tasks. Quality and shelf-life prediction for retail fresh hake (Merluccius merluccius). Buying Leads | Product Classification | To determine the melting point of the pentahydrate we focus on the middle part of the graph, when the pentahydrate temperature, despite continuing supply of heat, remains constant – the substance is melting. Disclaimer, Copyright © 2018 ChemSrc All Rights Reserved, sodium thiosulfate pentahydrate structure. Connect the temperature sensor to your computer and insert it into the container, so that its measuring element (its tip) stays immersed in the substance even after melting. 3). Melting Point Density Bulk Density Solubility Special Grade pH Value Physical Form. Selling Leads | Chemsrc provides sodium thiosulfate pentahydrate(CAS#:10102-17-7) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Sodium thiosulfate pentahydrate, glass container or tube, laboratory stand with brackets, temperature sensor cooperating with a computer (in the model experiment the Vernier Go!Temp sensor was used), burner or candle, matches. Chloroxyanion Residue Quantification in Cantaloupes Treated with Chlorine Dioxide Gas. It has a role as an antidote to cyanide poisoning, a nephroprotective agent and an antifungal drug. Sodium thiosulfate pentahydrate is a white crystalline substance with a melting point between 48 °C and 49 °C) which makes it ideal for this experiment. Biologically Active Compounds | Shanghai Jizhi Biochemical Technology Co., Ltd, sodium,1-(2-sulfonatosulfanylethylamino)octane, sodium,2-methanidyloxolane,sulfurothioic O-acid, Sodium hexamethylene-1,6-bisthiosulfate dihydrate. J. If we consider the parts of the graph in which the temperature increases to be linear, we can observe that the gradients of these dependencies are different – the temperature of liquid pentahydrate rises more slowly than of solid pentahydrate. Do not change the intensity of the flame during heating. After the measurement, the melted sodium thiosulfate pentahydrate can be disposed by pouring it into the drain. After the measurement, we obtain the following graph of temperature versus time (Fig. Formula: Na2S2O3.5H2O. About Us | When the crystalline substance is being heated, its temperature stops increasing after reaching the melting point; all supplied heat is used to break the structure of the crystalline lattice. Launch the programme for data collection from the temperature sensor and set the measurement time for at least 25 minutes. The goal of this experiment is to measure the temperature of sodium thiosulfate pentahydrate during heating and estimate the melting point of the substance. sodium thiosulfate pentahydrate MSDS(Chinese). Its melting point is 48.3 ̊C (118.94 ̊F), boiling point 100 ̊C (212 ̊F), density 1.67 g/cm3. Such temperature behaviour is indicated in the graph in Fig. 208 , 65-74, (2015). Thermal Conductivity of Plastic and Metal I. It is not necessary to monitor this experiment. It is evident that in the first part of the measurement the temperature increase is approximately linear, then the temperature stabilizes and at the end of the measurement, it begins to increase again. The table of contents will list only tasks having one of the required ranks in corresponding rankings and at least one of the required tags (overall). Sodium Thiosulfate Pentahydrate. Start the data collection and at the same time ignite the burner and set it to a very small flame. MSDS/SDS Database Search | Sodium thiosulfate pentahydrate is a hydrate consisting of sodium thiosulfate with 5 mol eq.
