#efflorescent

Efflorescent, deliquescent and hygroscopic compounds are terminologies used in chemistry to describe the chemical changes that occur in a compound during a chemical reaction. These changes are reflective of the kind of bonding present in the reacting elements, their oxidation numbers, their affinity for electrons and their ability to displace other elements. Efflorescent, deliquescent and hygroscopic compounds is also indicative of the ability of the compounds to absorb of crystallization. When pellets of sodium hydroxide, washing soda crystals that is gotten from an airtight container, concentrated tetraoxosulphate(VI) acid and quicklime are each placed on a watch glass after noting their appearances carefully. When you leave each of these substances in the open for a while, you would notice some visible differences in their appearance which is an indication of their ability to either lose or gain moisture from the atmosphere.   Efflorescence: A number of crystalline salts will lose all or part of their water of crystallization when they are exposed to the atmosphere to form a lower hydrate or the anhydrous salt. This phenomenon is referred to as efflorescence while the salt is said to be efflorescent. A perfect example of a compound that undergoes efflorescence is washing soda where its molecules lose nine out of its ten molecules of water of crystallization when it is exposed to the open air.           Na2CO3.10H2O(s) → Na2CO3.H2O(s) Read the full article

If you've ever rented out a property for a long period of time, you'll likely to have been concerned, at one point or another, about whether the tenant can be relied on to maintain the condition of carpets, walls and, of course, tiled floors. This customer, who owns a property in Windsor (home to Windsor Castle, one of the official residences of the Royal Family) had encountered this very problem. The property had been rented out to a tenant for the last five years, but the Slate tiled Read more at http://berkshire.tiledoctor.biz/rejuvenating-a-slate-tiled-kitchen-floor-in-windsor/

Returning to the property the next day, I ran some quick damp tests to check for any excess moisture that might have prevented me from sealing the floor. We will always do this as a precaution – especially with older floors that lack a damp proof membrane – because damp issues can damage the performance of the sealer and render it ineffectual. Thankfully, the floor proved try and I sealed the floor with Tile Doctor Seal and Go, which is an acrylic polymer sealer that provides an aesthetically pleasing low-sheen finish, as well as, of course, strong stain and ingrained dirt protection. As you can see from the photos above, the restoration really brought this Slate tiled floor back to life after five years of poor maintenance. The customer was very pleased to have it restored back to its optimum condition – ready for the property to be rented out again! Source: Slate Tile Cleaning and Restoration in Berkshire
