Sodium hypochlorite

Kennedi Wilson CHE 1121-010 TA Grace Samenuk 28 August 2015 Purpose of the Lab: Gathering a viable understanding of the basic practices that substantial in conducting experiments in a chemistry lab is critical. In such, the purpose of this lab is to exhibit such foundations through evaluation various ways of measurement as well learning to distinguish between properties and doing so via equipment provided in the lab. The types of measurement that will be highlighted include mass

This type reaction is known as a double displacement, where two ionic compounds, in this case lead nitrate, Pb(NO3)2(aq) and sodium iodide, NaI(aq), “change partners”. The cation (positive ion) of one compound combines with the anion ( negative ion) of the other to form two new compounds, one aqueous and one being an insoluble product known as a precipitate. To determine which

Determing the Chemical Equilibrium for FeSCN2+ by Observing Colour and Concentration Purpose: The purpose of this lab is to determine the equilibrium constant value of Iron (III) Nitrate with Potassium Thiocynate by observing colour changes when various substances are mixed with the Iron (III) Thiocynate and measuring the depths of 2 solutions after adding or removing some of the solutions until the colours match. Hypothesis: Part 1 If Iron (III) Thiocynate is mixed with distilled water in

Relationship between Reactants and Products Results and Discussion The starting material of the Calcium chloride (CaCl2) was varied with each of the five Erlenmeyer flasks, while the Sodium carbonate (Na2CO3) remained unchanged through the reaction according to the Lab Manual.1The reaction of Calcium chloride and Sodium carbonate in each of the Erlenmeyer flasks that occurred resulted in a cloudy blue and white mixture. Once the mixture was added into the suction filtration system created, a powder

We evaluated the impact of desmopressin and α1-blocker tamsulosin combined therapy in treatment of LUTS/BPH patients with noctuia. BPH is a common disorder, which affect about 40% of men older than 50 years. Nocturia is a common manifestation of BPH (6) that is not only bothersome but can also have a marked impact on sleep patterns and decreases the QoL (9, 10). Different treatment modalities for LUTS/BPH have been used with success. However, treatment for nocturia has been reported to be less satisfactory

healthy pH level. Electrolytes are lost through sweat, so it is important always have a source potassium during or after physical activity. Potassium is also important for the balance of blood pressure. It helps lower your blood pressure, along with sodium. Even though potassium helps lower your blood pressure, there are other things that affect it. Potassium is really important in for the ability for your skeletal and smooth muscles to contract. It also vital for the health of your heart. Without

increase in BP (17). Although Na+ associated with chloride had different effect, compared to when it is binding to other anion such as bicarbonatebut since 1904, it has been considered as as a major risk for CVD and BP, in the form of NaCl. (18). the sodium chloride might have more important role in

Discussion: There are numerous ways of isolating and purifying a substance, and an investigation of the differences of each procedure were performed. In two different procedures, lead nitrate and potassium iodide were used to isolate and purify pure solid lead iodide, and the differences in the limiting reactant and solid lead iodide was observed. The amount of solid lead iodide was calculated by the measuring the mass of which the solid lead iodide was created in before and after the purification

Chapter 9 1) Approximately how much water do you need each day to stay healthy? Water constitutes 50% to 70% of the human body. Its unique chemical properties enable it to dissolve substances as well as serve as medium for chemical reactions, temperature regulation and lubrication (found in the knees and other joints of the body); it also aids in regulating the acid base balance in the body. It helps remove waste from the body and is the basis for saliva, bile and amniotic fluid. It is

8. You Sit A Lot Did you realize you sit for around 67 hours every week? Which means you only move for around seven hours of your 24 a day. That means compared to 50 years ago you’re burning 100 calories less every day. If you think that doesn’t sound like much… well, it equates to 10 pounds every year. Get up and move around for a couple of minutes for every hour of sitting to offset the effect. Better yet, if you can stand while you work it’ll burn 50 calories more than just sitting down. So
