therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity is to the highest accuracy. The stock solution on the other hand‚ which is also a base in this experiment‚ is a large volume of

depends upon its composition. The determination of density is a nondestructive physical process for distinguishing one substance from another. The mathematical relationship is: Density= massvolume. Part A: 1. Find the blocks tab in the right hand corner. Click on the “Same Mass” tab. 2. Insert the blocks one at a time in the pool of water. Observe the change in the water level. a. Note: Only 1 block should be in the water at any given time. 3. Completely submerge the blocks

two fungi mate‚ the hyphae fuse together. The movement of the two fungal nuclei into one cytoplasm is known as dikaryon. Next‚ the cells go into karyogamy. The two nuclei fuse and provide diploid cells. These newly produced cells then go through mitosis and meiosis that cultivate spores (Campbell‚ 639). The spores are called ascopores and are found in a saclike structure that is the ascus. The spores germinate and form hyphae (Campbell‚ 64) Species of the genus Sordaria share a number of characteristics

Lab Report #1 Ahmad Dweik Question/Problem Which phase of cell division / mitosis is seen most often in whitefish blastula? Introduction Cell division is the process of a parent cell dividing into two daughter cells. Mitosis is a type of cell division. In mitosis a parent cells chromosomes are copied and separated into two cells with different nucleuses but same DNA. There are steps or phases that take place that make the cell divide. The first phase is called Interphase. In interphase

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Evaluation) These will be written up to demonstrate the links between practice and the supporting theory. Direct observation (2): Infection control. Assessment Hand washing is extremely important in clinical areas‚ as it reduces the risk of infections. Infections are caused by organisms which invade the host’s defence mechanisms. Effective hand washing can reduce the risk of infections occurring and protect the client. Patients have a right to be protected from infections and nurses have a duty to safeguard
