How to Grow Alum Crystals Background Information A crystal or crystalline solid is a solid material‚ whose constituent atoms‚ molecules‚ or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. The scientific study of crystals and crystal formation is crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. Potassium alum (Aluminum Potassium Sulfate) is the white crystalline natural

The cotton textile gets its glossiness by plunging it in myrobalan and milk mixture. Curves and motifs are then drawn with a pointed kalam soaked in fermented jaggery and water mixture. These layers are applied individually followed by application of natural vegetable dyes. After application of each colour‚ the textile is dried and washed. As a result‚ each cloth goes through about 20 washes. The specialty of Kalamkari paintings is that after the long tedious process‚ when the painting is completed

in the sample of scrap aluminum and when reacting with the aluminum produces hydrogen gas and aluminate ions 2 Al(s) + 2 KOH(aq) + 6 H2O(l) 2 KAI(OH)4(aq) + 3 H2(g) The limiting reagent in this reaction is aluminum since we are producing “alum” crystals. The excess reagent is KOH. This excess is necessary to help accelerate the reaction‚ therefore guaranteeing a maximum yield of crystals Then‚ after sulfuric acid has been added‚ a number of reactions will occur: The excess of potassium

Kalamkari the ancient Indian art of painting Kalamkari refers to a method of painting natural dyes onto cotton or silk fabric with a bamboo pen or kalam. The name kalamkari translates as pen (kalam) work (kari) in Hindi/Urdu‚ and was most likely derived from trade relationships between Persian and Indian merchants as early as the 10th century CE. European merchants also had names for this type of fabric decoration: the Portugese called it pintado‚ the Dutch used the name sitz‚ and the British preferred

synthetic fiber is best dyed with mayana-alum dye combination? 2. Often‚ mordants are added to fix the dye onto the fabrics. These are usually inorganic oxides or salts which form colored complex with the dye. Which mordant is more suited for dyeing cotton with dye extracted from eggplant skins? 3. Which mordant is more suitable for dyeing a synthetic fiber with the synthetic extract from mangosteen skins? 4. Which plant extract when combined with alum is suitable for dyeing a synthetic fiber

using cheesecloth. A clean‚ cotton cloth was then subjected to a series of procedures from pretreatment and mordanting down to dyeing with the rnangosteen extract. Alum and copper sulfate were used as mordants. Results revealed that the mangosteen extract was stabilized by both mordants‚ but copper sulfate was a better fixing agent than alum‚ because it intensified the color of

Analysis of Alum AlK(SO4 )2 . 12H2O AP Chemistry Lab # 5 INTRODUCTION Every compound has a unique set of chemical and physical properties. To identify a compound with certainty‚ experiments have to be conducted in order to verify these properties. Such kind of analysis is usually performed when a compound is synthesized‚ and whether the compound is indeed the compound desired needs to be ascertained. The main purpose of the experiment is to analyze alum‚ AlK( SO4 )2
