a) What is meant by a hydrate? b) What is an anhydrous compound? 2. Gas Hydrate Lab Activities Gas Hydrate Lab is actively involved in thermofluidic simulations and experiments for broad research areas of energy, environment and water resources. In order to determine the percent composition and the empirical formula of a hydrate, you must know how much water is in the hydrate. (Hint: the Lab group Mass before heating 1. The anhydrous (without water) form of the salt is produced when all the water of hydration is lost. To do this, you will need to heat the hydrate with a ame in order to evaporate the water (see Figure 1). Observing our nitrate, it has a white crystalline Processing Your Lab Data Show your work, include units, and write your answers in the blanks on the right. They are known as “hydrated salts”, or simply, hydrates. By measuring the initial mass of the fully hydrated compound and then re-weighing the fully dehydrated desiccant, the mass of water in the hydrate can be determined. Materials: Crucible Crucible Tongs Balance Clay Triangle Iron Ring Bunsen Burner Salt Crystals Striker Ring Stand Hot Pads Safety: Always wear goggles and handle the crucible with tongs as it will be hot. Heat the porcelain dish briefly to make sure that it is dry and then allow it to cool. Calculate the percent water in the unknown. Lab Exercise: Percent Water in a Hydrate Introduction: A hydrate is a crystalline solid that traps water as part of its crystal structure. The ratio of water molecules to the ions of the salt is a constant. What percentage of water is found in CuSO 4 * 5H 2 O? 2. Place the crucible on the clay triangle and.
The water molecules are not actually part of the formula, so the formula is written slightly differently. 3) Record your observations of the hydrate (color, texture, odor, etc. Heat can be used to dehydrate a hydrated salt causing the H 2 O molecules to Experiment 5 – Percent Water in a Hydrated Salt Pre-Lab Hints 1. MX nH 2 O salt water n = is the ratio of moles of you leave the lab each day. The solid remains unchanged except for the loss of the water. Record the mass of the crucible and the hydrate to four decimal places on the data sheet. Weigh the dish on the balance recording the mass in the data table. of these hydrates to act as a reference guide for your experiment. Purpose: To find the percent of water in a given Hydrate and then calculate the Empirical Formula for the Hydrate. laboratory, as well as ensued impacts of hydrate morphology on the physical properties of hydrate‐bearing clays. The unknown hydrate may be any of the compounds in the table on the design page. Materials: 1 Hot Plate 1 Wire Mesh 1 Small beaker 1 Glass Stirring Rod 1 Beaker Tong 1 Spatula Copper II Sulfate Hydrate (approx. An unknown hydrate may be one of the three hydrates listed in the table below. A summary of the activities is presented below: Research Area: Storage and Transportation Project Title: Enhancement of CO 2 Storage in hydrate form using additive Lab - Determining the Chemical Formula of a Hydrate Some ionic compounds form crystalline structures that trap water molecules within the crystalline framework. Formulas for hydrates are written using a dot convention: a dot is used to separate the formula of the salt from the formula of the water of hydration. Calculate the missing items in the table.

Of these, the most relevant software that we are going to talk about areīoth of them are Process Simulation Software. Since then, AspenTech has been creating a lot of products, mostly in the following branches: This included divestment of batch and continuous simulation systems and integrated engineering software business (AXSYS). It was born out a joint research project between the Massachusetts Institute of Technology ( MIT) and US Department of Energy-an Advanced System for Process Engineering (ASPEN) Projectįun Fact: On July 15, 2004, AspenTech was required by the Federal Trade Commission to make divestitures in regard to an anti-trust ruling against its acquisition of HyproTech (they worked on HYSYS). From wikipedia: AspenTech wasFounded in 1981.
