Understand The Difference Between A Softener And Conditioner When Treating Water In Your Home A water conditioner is an appliance that treats the water in your home in some way to improve its quality. A water softener is a type of conditioner that works specifically to reduce hard water. Whether you buy a conditioner or softener depends on what you want to achieve with the water. Water Softeners Alter Minerals With Salt If your water has excess minerals‚ it’s called hard water. The minerals leave

Aim: To find the solubility and the solubility product of calcium hydroxide. Theory: Define‚ with equation‚ the solubility product. Find‚ from literature‚ the solubility product of calcium hydroxide at 25oC. Experimental: Reagents: solid calcium hydroxide‚ water‚ 0.1 moldm-3 hydrochloric acid Apparatus: Procedure: 1. An empty bottle was weighed. Then the empty bottle was weigh with 1g calcium hydroxide. 2. 100 cm3 of distilled water was added to the bottle. For about

Volumetric Determination of Impure Sodium Carbonate (Na2CO3) Introduction: To determine the total amount of carbonate in unrefined sodium carbonate‚ soda ash‚ a titration is done using a standardized solution of HCl. Aqueous HCl is a strong acid and therefore almost completely disassociates into H+ and CL-. Therefore‚ when HCl is used in a titration‚ the H+ is the titrant. Carbonate in aqueous solution is able to accept a proton‚ i.e. it acts as a base. When carbonate accepts the H+ a bicarbonate ion is

water and stir to form the calcium chloride solution. Use only distilled water since tap water may have impurities that interfere with the experiment.. Use stoichiometry to determine how much Na2CO3 you will need for a full reaction. * Weigh the calculated amount of Na2CO3 and put it in a small paper cup. Add 25 mL of distilled water and stir to make a sodium carbonate solution. * Pour the sodium carbonate solution from the paper cup into the beaker with the calcium chloride solution. A precipitate

What is heartburn and when does it occur? Heartburn occurs when hydrochloric acid‚ which is used to digest food in the stomach‚ backs up into the oesophagus causing an irritation. Normally the oesophageal sphincter would close tightly‚ not allowing the acid to back up. If this valve‚ however‚ is not functioning‚ the acid can slip by. Occasionally heartburn can be associated with hiatus hernias. Describe how the heart remedy works‚ including a description of what a neutralisation reaction is

give way in answering this threat. A trash-like shell can be used and recycled in anyways‚ maybe in making tiles. Most kind of trash-like shells is eggshells because this is the only shell with less usage. Eggshell contains calcium carbonate that can give or produce calcium hydroxide‚ in the form of lime‚ when burn. This lime can be used to produce tiles. But the problem‚ is eggshell can be a component of making tiles? Background of the Study This study was conducted to ensure another component

Limestone is a sedimentary rock composed largely of calcium carbonate (CaCO3). Many limestones are composed from skeletal fragments of marine organisms such as coral or foraminifera. Limestone makes up about 10% of the total volume of all sedimentary rocks. The solubility of limestone in water and weak acid solutions leads to karst landscapes‚ in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock. Limestone has numerous uses‚ including
