Reacting Acids and Bases Lab Report Introduction Every liquid‚ except for distilled water‚ has either acidic or basic traits. An acid is sour tasting‚ and gives a sharp stinging pain in a cut or wound‚ and bases taste bitter‚ and feel slippery. A pH scale is used to determine what traits a liquid has; acidic or basic. The scale focuses on OH- (hydroxide ions) and H+ (hydrogen ions). The scale goes from 0 to 14. 7 is distilled water‚ as it is directly in the middle; neither acidic or basic. Acids are

article describes a technique for processing liquid radioactive waste water using membrane techniques to single out only radioactive waste components without affecting the salt ballast. This solution dramatically reduces the amount of radioactive concentrates to be long-term storage‚ and provides an opportunity to re-use treated water and chemicals. Keywords. Liquid radioactive waste‚ radioactive waste water purification‚ reverse osmosis‚ selective extraction of radionuclides. Introduction. To radioactive

basic or neutral. This is possible because in solutions of different pH‚ the colour of the inidcator will change simultaneously with pH change. This is made possible by pigments in the indicators. Hand made indicators include universal indicator‚ methyl orange‚ phenolphthalein and many more. Acids and bases are diverse in this world. They are everywhere ranging from foods to trees to rocks and many more. Indicators can be used to determine whether these substances are acidic‚ basic or neutral. Manufactured

between specific limits moisture contents. Below these levels they have a solid consistency and above a liquid consistency. Therefore‚ the soil has two important properties to be analyzed‚ the Liquid Limit (LL) and the Plastic Limit (PL). The Liquid Limit is the moisture content that makes the soil has a liquid behavior. The Plastic Limit is the moisture content below which the soil becomes from the plastic state to the semi-solid state‚ which means it loses the ability to be shaped and starts to become

Determining the Molar Mass of a Volatile Liquid Purpose: The purpose of this lab was to find the molar mass of a volatile liquid. Data Table: Mass of Test Tube and Stopper (g) | 10.864 g | Barometric Pressure (mmHg) | 749.31 mmHg | Temperature of Boiling Water (C) | 97.1 C | Mass of Test Tube‚ Stopper‚ and Condensed Liquid (g) | 10.890 g | Volume of Flask (mL) | 9.90 mL | Calculations: 749.31 mmHG*1 atm760 mmHg= .98593 atm 9.90 mL*1 L1000 mL= .00990 L 97.1 C+273=370.1 K Substituting

Acids and Bases Are Everywhere Every liquid you see will probably have either acidic or basic traits. Water (H2O) can be both an acid and a base‚ depending on how you look at it. It can be considered an acid in some reactions and a base in others. Water can even react with itself to form acids and bases. It happens in really small amounts‚ so it won’t change your experiments at all. It goes like this: 2H2O --> H2O + H+ + OH- --> H3O+ + OH- See how the hydrogen ion was transferred? Most of the

It achieves its intended aim by using sexual puns and hunky men to target women while promoting their product at the same time. To begin with‚ Liquid-Plumr is a drain cleaning product that gets rid of tough clogs. According to Clorox (n.d.)‚ Liquid-Plumr Urgent Clear‚ a powerful gel drain cleaner‚ is designed to clean the toughest

Abstract This work describes the extraction of caffeine from tea leaves to determine its % caffeine. The extraction process selectively dissolves one or more compounds in a mixture into an appropriate solvent. In this experiment‚ it was visible in the process wherein the components of the tea leaves were dissolved in two solvents‚ water and dichloromethane (DCM)‚ with DCM used for multiple extractions. The organic layer was evaporated and the determined % caffeine was 0.12%. Furthermore‚ the purified
