Back titration determination of the carbonate content in …

An extra 10ml of distilled water was added and the solution heated to boil and then allowed to cool for about 10mins. The content of the conical flask after heating was then transferred into a 100ml volumetric flask and topped up to the mark. 10ml of the prepared solution in the volumetric flask was measured and titrated against standard sodium hydroxide (0.1M) using 2 drops bromothymol blue

Chemistry in a Ziploc Bag ( th Grade) - Vanderbilt University

• Calcium chloride - It is put on roads in winter because it lowers the freezing point of water, preventing ice from forming. - It is commonly used as an electrolyte in sports drinks and other beverages, including bottled water.

Calcium Carbonate Phosphate Binding Ion Exchange …

In addition, laboratory rate law formulation of calcium carbonate reacting with aqueous phosphate was conducted using pH balanced sodium phosphate solutions (Sigma-Aldrich Company). Differing phosphate concentrations were treated with differing amounts of a saturated calcium carbonate solution to find a minimum amount of calcium carbonate needed to reduce a maximal amount of phosphate.

Super Water-Absorbing Polymers | Carolina

Super water-absorbing polymers are polymers that absorb several hundred times their own weight in water. The structure of these polymers accounts for their water-absorbing capacity. The polymers consist of long strands of molecules covalently bonded (or cross-linked) together.

REACTIONS OF ALCOHOLS - North Toronto Collegiate Institute

• Like water, alcohols can act as an acid or base, depending on what it is reacting with. • When they react as an acid, the alkyl oxide ion (R-CH2O-) is formed. ethanol + sodium ethoxide ion + sodium ion + hydrogen 2 CH3CH2OH + 2 Na 2 CH3CH

Calculating the Solubility Product of Calcium Hydroxide

Calculating the K sp of Calcium Hydroxide Introduction Calcium hydroxide, Ca(OH) 2, is an ionic solid that is slightly soluble in water.A saturated solution is an equilibrium, that can be represented by the following equation: Ca(OH) 2 (s) Ca 2+ (aq) + 2OH-(aq)

The chemical reactions taking place in your swimming pool

The water in pools has to be disinfected to make it safe for swimming. But the disinfectants added to pools aren’t just killing harmful microbes. They’re also reacting with organic

Preparation of salts and solubility of salts - IGCSE And IAL …

Answer: If we recall, we can see that calcium sulfate is insoluble in water. When the calcium carbonate reacts with the sulfuric acid, the insoluble calcium sulfate forms a layer of insoluble calcium sulfate around the calcium carbonate, which prevents the acid from getting to the calcium carbonate and reacting …

Tap water that is "hard" because it comes from wells and has been in contact with limestone for a long time contains relatively large amounts of calcium and bicarbonate ions. When this water is heated in coffee pots or water heaters and allowed to cool, limy deposits called "boiler scale" build up.

Lab Report: Extraction of Caffeine from Tea Bags …

Because caffeine is water-soluble and is a base, sodium carbonate must be added to the hot water to prevent it from reacting with the acids present and to ensure it remains a base. A liquid-liquid extraction was then performed to extract the caffeine from the mixture by adding dichloromethane.
