Lab Report – Strong Example Problem/Question Does using a base coat before painting nails prevent chipping? Background Information When painting nails‚ some manicurists use a base coat before applying the polish. The purpose of a base coat is to help the polish stick to your nails more easily. Base coats also help to protect your natural nail from the staining effects of colored polishes. Ridge-filling base coats fill in the grooves and cracks in the nail to create a smoother appearance

Lab 3 : Techniques in Microscopy Title : Preparation of light microscope observe cell organisms. Objective : To observe and investigate the cell structure under the light microscope. Introduction A microscope is an instrument used to magnify and resolve a specimen. It is important to know several important features of microscopy which involves magnification‚ resolution and contrast. Magnification is the enlargement of a specimen while resolution is the ability to distinguish detail or the

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

Many are structural components of bone‚ muscle‚ hair‚ tissue‚ etc. Others are enzymes that speed up cellular reactions. All proteins are made up of amino acids (Johnson‚ 2010). The purpose of this experiment is to determine whether peptide bonds are present in various food substances. The color violet will indicate the presence of
