Determining the Unknown Concentration of NaHCO3 (aq) Through Titration Introduction Titration is the accurate addition of a titrant- solution in a burette- into a measured volume of a sample (Kessel‚ 2003). There are many different types of titration‚ such as acid-base reaction‚ redox reactions‚ precipitation reaction and more (Dohrman). In this lab an acid base titration will be explored. In an acid-base titration‚ the concentration of an acid or base is unknown and is determined by the adding

The 13C NMR spectrum was useful to help finding the structure of the unknown. It showed six different signals in the spectrum. Signal 1 had an observed peak value of 19.242 ppm‚ and its peak calculated value was 19.1 ppm. This signal was first to most upfield and shielded in the spectrum because of the high electron density of carbon. This signal was agreed to a literature value for a CH3 group between 5-30 ppm. Signal 2 was branched to signal 1‚ and had the same value‚ but it was agreed for the

GPS and GSM for Accident Spot Identification ABSTRACT: The main intention of this project is to find the accident spot at any place and intimating it to ambulance through the gps and gsm networks. Now-a-days‚ it became very difficult to know that an accident occurred and to locate the position where it has happened. It’s very difficult for the lives of victims until anyone noticed and informed it to the ambulance or to any hospital and

Sally Jessica Smithers: The Case Of The Unknown Assassin Sally Jessica Smithers was a slender‚ beautiful‚ smart‚ and talented cop. She was investigating eleven serial killings of important men when she got a call‚ there was another murder. When she went‚ she took no time at all at the scene. As Sally left the crime scene in the park‚ with one hand in her long dark brown hair‚ she called out to a few units to make three immediate traffic stops and went to the last one to read off people’s IDs.

Scheme of Analysis for Lab 2 Unknown Sample Description Phase‚ color‚ odor‚ crystalline or gel-like? If crystalline‚ what is crystal shape – needle-like or powdery? Does it look like a pure substance or a mixture? How many components appear to be present? Tests on original sample Flame Test Bushy yellow‚ orange flame – Na+ is present and possibly K+ and NH4+. Pink-purple flame – K+ is present and Na+ is not. (Possibly NH4+) No color or faint trace Na+ - NH4+ is possible‚ K+ and Na+ are

Partial fingerprints identification can be hard‚ because not knowing the whole print can be misleading and given the wrong person. Their is no scientific bases that no two people have the same fingerprint or how alike they have to be to send an accused to jail

Evaluation of techniques for Dental and DNA identification for mass disaster victim Introduction: A mass disaster is an unanticipated event that results in serious injury and death to a large number of people. Mass disaster can be categorised into three categories‚ natural disasters‚ accidental disasters or even intentional terrorism acts. Natural disasters could include events such as earthquake‚ flooding or tsunamis. Accidental disasters could be associated with events aircraft‚ ship
