Title: Determination of Water Hardness Using a Titrator Purpose: To become familiar with the concept of water hardness‚ practice a titration technique using a titrator‚ and determine the hardness of the local water supply. Procedure: 1. Gather the test tube holder‚ small stopcock‚ 10-mL syringe (titrator)‚ and 2 thick textbooks and the LabPaq box or 5-6 thick textbooks. 2. Remove the plunger from the titrator and place it back in your LabPaq box. 3. Attach the stopcock to the tip of

CaCO3 K2CO3: 9.25 g x 1 mol / 138.2 g = 0.07 mol CaCO3 CaCl2 is limiting reagent Theoretical yield = 0.06 mol CaCO3 x 100 = 6.40 g CaCO3 Percent yield = 6.15 g / 6.40 g = 96.1 % Post-Lab Questions 1. In this first trial‚ I saw that there was less calcium carbonate that was produced. 2. The results were expected because less reactant was used in the first trial compared to the second trial. 3. Reducing the amount of CaCl2 used would still keep this substance as the limiting reagent and therefore

A certain amount of bone is always being broken down and reformed‚ in order to help the body balance its calcium levels. Normally‚ these two processes happen at the same speed‚ so there’s no overall change in bone mass. When a person develops osteoporosis‚ their bone tissue is breaking down faster than it can be reformed‚ so the bones start become brittle and

Standardize the solution by using a 10 mL transfer pipet to add 10 mL of standardized calcium ion stock solution to a 250 mL Erlenmeyer flask and mixing it with 30 mL of deionized water. Add 3 mL of ammonia/ammonium chloride buffer (pH 10) to ensure that the calcium ions remain in the solution for accurate results. Add four drops of Eriochrome Black T indicator solution so that a color change can be visible during titration

After reading Arthritis Research UK’s online pamphlet article on osteomalacia I feel very informed about this skeletal disease. This article had everything I needed to know. It told all about the disease‚ what it is‚ what causes it‚ who is at risk‚ research and more. I learned that osteomalacia means soft bones‚ and that is exactly what the disease is. The mineralization in the bones does not happen properly‚ causing bones to be made up of a collagen matrix with no mineralization covering. This causes

Calcium is essential to health yet it holds a hidden danger that brings us to our graves much quicker then we would like. Calcium is the most promoted nutrient by proponents of conventional‚ nutritional‚ and alternative medicine. This is a great and tragic mistake. They should have been promoting magnesium. Magnesium deficiency leads to an increase in myocardial levels of both sodium and calcium. This is a problem because Coronary Artery calcium is a predictor of near-term coronary heart disease
