Calcium hydroxide

Sodium bicarbonate (NaHCO3), or sodium hydrogen carbonate, also known as baking soda and bicarbonate of soda, is a soluble white crystalline compound, with a slight alkaline taste resembling that of sodium carbonate. It is found in many mineral springs, in natural deposits in USA and is mainly produced by the Solvay process: NaCl + NH3 + CO2 + H2O NaHCO3 + NH4Cl Sodium bicarbonate, when exposed to an acid, releases carbon dioxide and water: NaHCO3 + HCl NaCl + H2O + CO2 (gas) Above 70°C,…

To first perform this experiment a beaker of water was set to boil on a hot plate while samples of serum and benedicts reagent were collected. Six test tubes were gathered and labeled by which blood vessel the serum was collected from and by which category, either postprandial or fasting. Then by using a metric ruler two measurements were placed on the bottom of each tube, one at one centimeter and one at two centimeters. This was to indicate how much serum and Benedict’s reagent to use,…

PH levels are a measure of how acidic or basic your beverage is. They show what beverages are more acidic, like soda, and what beverages are more basic, like water. It’s measured on a scale from one to fourteen. One through six are the acid levels, seven is the only neutral level, and eight through fourteen are the basic levels. First, get 2 drinks of choice and pour them into two different cups. Then, record its pH level, as well as the room temperature. Next, take another liquid and mix it…

1) Primary standard: primary standard is a highly pure compound which is a reference for identifying the concentration of a known compound in titration. Titrant: in titration; titrant is a solution whose concentration is known. When there is an unknown solution (analyte), titrant is used for identifying the concentration of that unknown by adding titrant to analyte. (using burette) Acid –base indicator: acid- base indicator is an indicator that determines the pH of a solution by changing its…

If a quantitative solution needs to be prepared, there are a series of steps that must be followed in order to get accurate answers. there are several objects needed to prepare it, including a 500 ml graduated cylinder, deionized water, and sodium phosphate dodecahydrate as the aqueous solution. The first step is to find the mass of the solution, sodium phosphate. In the formula, sodium's atomic mass is multiplied by 3 because there is the original weight times 3 atoms of sodium in the formula.…

The sequence of the reactions employed for the construction of novel indole–benzimidazole-based 1,2,3-triazole hybrids is demonstrated in Scheme 1. Compound 2 was prepared by treating propargyl bromide with 1H-indole-3-carbaldehyde (1) in presence of potassium carbonate in dry acetone at reflux temperature [26]. Compound 2 was further reacted by heating at reflux temperature with o-phenylenediamine (OPDA) in chloroform for 6 h afforded compound 3. Compound 3 coupled with variously substituted…

The propylene glycol is considered to be one of the common organic compounds which can be used in many life applications. It can be used in antifreeze, pharmaceuticals and many applications as well. It can be produced by hydrolysis of propylene oxide that is accelerated by the catalysis of base or acid. The goal of the experiment is to produce propylene glycol using water and propylene glycol as a reactant to synthesis propylene glycol. The purpose of doing this experiment is to converge and…

Jessica Vandeventer April 13, 2016 Energy Comparison of Fuels Purpose/Question- The Purpose of the lab is to see a comparison of fuels using a home made calorimeter. Hypothesis– The burner fuel is going to be a better source of fuel than the tea candle. Data Tables/ Graphs – Data Table 1. Mass and Density of Distilled Water. Mass of 10.0 mL of distilled water (g) Density of water (g/mL) 9.2g .92g/mL Data Table 2. Calorimetric Data. Fuel Source: Initial mass of fuel (g) Final mass of fuel (g)…

MATERIALS AND METHOD FOR BURN SCAR BIOMECHANIC BURN WOUND GENERATION All experiments and data collection were performed following approved protocols of the Ohio State University Institutional Laboratory Animal Care and Use Committee. A female red Duroc pig was maintained on standard chow ad libitum and being fasted overnight at other piggery. The animal had been anesthetized with Telazol and isoflurance. Anesthetic is a rapid and reversible drug-induced change in behavior or perception. Then…

Vinegar Dilute and Impure Acetic Acid or better known as vinegar is a compound formed by the chemical reaction of carbon, hydrogen and oxygen. The composition of vinegar is acetic acid (C2H4O2) and water. Also, the formula for this compound is CH3COOH. These elements are nonmetals,so the type of bond that this substance made is covalent. Vinegar has many kind of properties and utilization in several ways. For example, it can be use for food preparation, cleaning and health. When added in…
