It’s intended for intravenous administration‚ but if a suitable vein cannot be found it can be given orally which has an unpleasant taste. It is made up of NaCl (sodium chloride)‚ NaC3H5O3 (sodium lactate)‚ CaCl2 (Calcuim Chloride)‚ and KCl (potassium Chloride). Lactated Ringer’s has a pH of 6.5‚ but is an alkalizing solution. Therapy Lactated Ringer’s solution is used to induce urine output in patients with renal failure‚ and to supply water and electrolytes either with or without calories

history Sensodyne was first marketed in 1961 as the first desensitising toothpaste based on a strontium chloride formulation. About 20 years later‚ in 1980‚ Sensodyne toothpastes containing a new potassium nitrate formulation were launched. Besides being a leader in treating dentine hypersensitivity‚ the Sensodyne brand expanded in 2006 with the launch of Sensodyne Pronamel to help protect against the effects of dental erosion. Sensodyne is globally recognised as a specialist toothpaste for sensitive

Complexometric Determination of Water Hardness Lab Report Introduction: In this lab the use of disodium salt of EDTA is used to determine the concentration of M^2+ metal ion impurities in hard water by chelometric titration. The indicator Eriochrome Black T will help detect when you EDTA has completely chelated the metal impurities. Chemical Principle: A complex ion consists of a metal ion with Lewis bases attached to it. These Bases form strong covalent bonds with the central complex

wavelength — the distance between the crests of the waves — or its frequency — the number of crests that pass by in a given amount of time.The higher the energy of the radiation‚ the shorter its wavelength and the higher its frequency will be. Blue light‚ for example‚ has a higher energy and therefore a higher frequency and shorter wavelength than red light Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colours

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength

Flame test: AIM: To determine which part of the salt is responsible for the characteristics in the flame. HYPOTHESIS: If we introduce a metal salt in the blue flame of the Bunsen burner‚ then the colour given off by the flame is due to the metal part of the salt. METHOD: (1) With a heat proof mat under the Bunsen burner‚ turn the gas on and light up the Bunsen burner with matches. (2) Pour enough Hydrochloric acid into a beaker. (3) Using your wire‚ dip it into the beaker containing Hydrochloric

Being the most abundant and important compound to life‚ living organisms would not exist without water. Within the human body the majority of biological reactions require water to take place. Although it is possible for human survival without nutrients for up to several weeks‚ without water humans would die in a matter of days. In the human body‚ water makes up 60-70% of adult body weight. At cellular level water makes up between 70-95% of the mass of a cell. The amount of water in the human body

Procedure: The first part of this lab involved the standardization of the base NaOH with potassium hydrogen phthalate‚ or KHP. First‚ about 400 mL of NaOH (10 M) were poured into the 600-mL beaker. This was used to fill the burette. The 50-mL burette was rinsed through twice with 5 mL of NaOH. Then‚ the burette was mounted on the ring stand using a burette clamp and filled to 0 mL. Some of the NaOH was drained to fill the tip of the burette. The initial volume of NaOH‚ rounded to two decimal places
