unknown was scooped onto a nichrome wire loop. The wire was held in the flame to determine the cation. To compare the unknown’s flame color to a known cation’s flame color‚ a sample of known compound were taken to perform a flame test. The cation barium burned a pale green color at a low intensity. The cation calcium

Standard Solution (Part A and B) ABSTRACT The purpose of this experiment is to prepare a standard solution of potassium hydrogen phthalate and use titration to perform an acid/base reaction between the potassium hydrogen phthalate and sodium hydroxide to standardize approximately 0.10 M sodium hydroxide solution. To prepare the Potassium Hydrogen phthalate‚ a 2.00 grams of KHP was measured to an accurate measurement of 1.980 grams. A total of 100 mL of water was mixed with the KHP solution

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment

hollow block in making buildings but this research aims to make a more durable and fire retardant hollow block in making infrastructures. Background: The glass contains lime‚ magnesium oxide‚ and aluminum oxide that add more durability. Barium also increases the refractive index and low dispersion that make it endure shock. Plastics contain stabilizing additives that include fire retardants to lower the flammability of a material. These 2 combined with the components of making a hollow

“The Happy Prince” is a fairy tale Oscar Wilde wrote for his two sons but its educational and humane value go far beyond the fairy world of children. The story develops children’s compassion and sympathy for the poor and makes adults look back on their attitude toward the unfortunate people around them. All the good actions of the Happy Prince are so worthy and touching that he deserves our respect and admiration. The Happy Prince’s actions of helping the poor are worthy of respect. Without the
