A hydrate has a definite number of water molecules bound to each anhydrous salt unit. The formula of the hydrate copper(II) sulfate pentahydrate is CuSO4 · 5 H2O The dot indicates that the molecules of water are attached to the ions in CuSO4 by weak bonds. We can drive off the water of hydration by heating the hydrate. If blue CuSO4 · 5 H2O is heated‚ the water of hydration is released as water vapor‚ and solid white anhydrous CuSO4 remains.

Lab 5 Acid/Base Extractions Introduction The purpose of this experiment is to separate either the organic base (amine) or organic acid (carboxylic acid) from a mixture that contains inorganic impurities (salt) by performing a liquid-liquid extraction and then taking a melting point. Key Experimental Details and Observations Our starting material‚ Compound B‚ was a fine white powder and weighed 0.535g. The final product was a shiny white sheet that resembled acrylic paint and weighed 0.109g

Chamberlin Date: 29 April 2017 Experiment Title: Acid-Base Titration Abstract: Vinegar is a common household item containing acetic acid as well as some other chemicals. This experiment is designed to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH. CH3COOH(aq) + NaOH(aq) -> CH3COONa(aq) + H2O(l) By adding the sodium hydroxide‚ which is a basic solution‚ to the acetic acid‚ which is an acidic solution‚ a neutralization

In order to find the Vitamin C content you will need to use a process called titration which‚ according to the Columbia Electronic Encyclopedia‚ is when you add a chemicals to a liquid in order to create a reaction which can determine the content of a substance inside the liquid. This is how you will find the Vitamin C content of different juices. Iodine will be added to the juice‚ which will create a reaction that can help determine the Vitamin C content. To start‚ pour 30 milliliters (mL) of Lugol’s

Type of kafalah in general‚ kafalah contract may be classified into two categories 1. Kafalah bi al-mal‚ it is a guarantee for property or finance; 2. Kafalah bi al-nafs‚ it is a guarantee for one’s self Kafalah bi al-mal may be divided into three main categories as follows: 1. Kafalah bi al-dyn‚ it is a guarantee for a debt owned by a party. It is meant to guarantee for the settlement of the debt by the guarantor should the guaranteed party is in default; 2. Kafalah

Ashley Spees CHM 261- Batzer Chem Final Write Up- Kool Aid Lab Total Acid This part of the lab requires titration of Kool Aid with an NaOH solution. The reason titrations are used is to determine the concentration of an unknown solution by reacting a strong acid with a strong base. Titrations are hard to accomplish‚ though‚ due to the fact that indicators used to show the endpoints are very sensitive and one drop could make the solution titrate past its endpoint. Blue stock solution: 3 mg/L
