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

Acids vs Bases In chemistry‚ when some elements are mixed‚ the compounds that are formed can be classified depending on its characteristics‚ just like acids and bases. Acids are defined as compounds that donate a hydrogen ion‚ H+‚ to another compound. Bases are the chemical opposite of acids. They both are different in many ways. One way in which acids and bases differ is the pH and the pOH. The pH is a number used to denote the hydrogen-ion concentration‚ or the acidity‚ of a solution. In the

The Mt. Everest Base Camp is a dream goal for the vast majority of the trekkers and explorers around the globe. There were a few endeavors to make summit to the Everest for leaving impressions on the famous base camp of Mt. Everest (5364 m) like the legendary Sir Edmund Hillary and Tenzing Norgay- Mt. Everest climbers. However‚ many of them vanished or passed on amid the journey. New Zealand national Hillary and Nepali resident Sherpa were sufficiently fortunate to successfully have the summit to

Radiations of GSM Base Station Antenna And Its Health Consequences- A Research conducted in Nigeria In Nigeria 98% of Global System for Mobile (GSM) base stations (cell sites) are sited within 20 meters from residential‚ offices‚ schools‚ business buildings. Cell phone antennas emit microwave frequencies‚ which are non-ionizing radiation. A research was conducted by measuring field data of radiation from GSM base antennas in Nigeria for supporting evidence public health risks from gsm radiations

Name: Amanda Anile Course: CHM 101 (E05N)-NVCC Professor: Mihaela Chamberlin Date: 29 April 2017 Experiment Title: Acid-Base Titration Abstract: Vinegar is a common household item containing acetic acid as well as some other chemicals. This experiment is designed to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH. CH3COOH(aq) + NaOH(aq) -> CH3COONa(aq) + H2O(l) By adding the sodium hydroxide‚ which is a basic
