recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below. As you can see from Equation 1‚ the acid-base reaction produces carbon dioxide (CO2) gas. This gas is what makes the fizzy bubbles

Determination of Gatifloxacin and Ornidazole in Tablet Dosage Forms by High-Performance Thin-Layer Chromatography 43 A simple and sensitive high-performance thin-layer chromatography method has been developed for the quantitative estimation of gatifloxacin and ornidazole in its combined dosage forms. Gatifloxacin and ornidazole were chromatographed on silica Gel 60 F254 TLC plate using n-butanol: methanol: ammonia (6 M) (8:1:1.5 v/v) as the mobile phase and scanned at 302 nm using a Camag TLC Scanner

5-tetrachlorobenzene) into its components by extraction. The mixture is dissolved in diethyl ether (common name is ether). Both components are soluble in this solvent. Then a 1 M NaOH solution is used to extract the benzoic acid in the form of its water-soluble salt‚ sodium benzoate (three extractions to ensure complete removal)‚ leaving the neutral compound in the ether layer. The three aqueous extracts are combined and the two components are recovered as follow: 1. The neutral compound by washing‚ drying and evaporating

surfactant modified alumina template was prepared by precipitation method previously reported in literature []. Typically‚ Precursor solution and surfactant solution were prepared by dissolving required amount of aluminium nitrate nonahydrate and sodium dodecyl sulfate in distilled water. Molar composition ratio of both the aluminium precursor and surfactant solutions was taken as 4:1. Mixture was stirred for 15 minutes at room temperature then precipitation was carried out by gradual addition of

Introduction: The purpose of this lab was to separate and purify a compound. This was achieved using techniques that allowed the extraction of the acid‚ the isolation of the neutral compound and the melting point classification of the neutral compound to test the purity of the sample. Chemical Reactions: HA + OH- A- + H2O R-COOH + OH- R-COO- + H2O Organic Acid Insoluble in H2O Conjugate base Soluble in H2O Procedure: A 0.170g sample consisting of a mixture of 0.110g

Marie Alessandra T. Reyes Group 4 18L Quantitative Determination of the Acidity of Soft Drinks I. Introduction Soft drinks are well known beverages among the young that are consumed mostly for pleasure. These beverages normally contain flavoring‚ sweeteners coloring‚ carbonic acid and acids. Carbonic acid and acids play an important part in the formulation of soft drinks. They enhance the flavor and give a pleasant refreshing ’lift ’ to the drink. The type of acid used can even affect the palatability
