1. Standarization of NaOH with Potassium Hydrogenphthalate (KHC8H404) The hygroscopic nature of NaOH requires its solution to be standardized with a stable primary standard such as potassium hydrogen phthalate. The exact molar concentration of NaOH solution can then be accurately determined. 1.1) Prepare the stock NaOH solution by dissolving about 4 g of NaOH pellet in 100 mL of deionized water. Note that NaOH is a hazardous chemical which is corrosive to skin and irritant to eye‚ be cautious and

IX. CONCLUSION Overall‚ our hypotheses were proved to be mostly correct. We believe that if the amount of sodium citrate is too low or too high‚ the sodium alginate solution would not form into a ball. The recommended amount of sodium citrate to be added to the sodium alginate solution was ⅛ teaspoon‚ or 0.5 grams. We supposed that if we exceeded this measurement‚ the sodium citrate would unbalance the whole solution‚ making the balls deform. If we added too little of the sodium citrate‚ we thought

The starting material for this lab was the dialyzed sample (stored at -20ᵒ C) from the previous lab. The CM sephadex resin (taken in a 50 mL tube) was already made swollen using Buffer C (20 mM HEPES‚ pH 7.9; 1 mM EDTA; 50 mM KCl). The dialyzed sample was thawed to the room temperature and gently poured over the resin. The tube was capped and kept on a rocker at room temperature for 1 hour. The tube was then centrifuged in a HS-4 rotor at 2500 rpm (1200g) for 5 minutes at 4ᵒ C. Supernatant was discarded

Introduction: Wi-Fi‚ an acronym for "Wireless Fidelity"‚ is a set of product compatibility standards for Wireless Local Area Networks (WLAN) based on the IEEE 802.11 specifications. Wi-Fi was intended to be used for mobile devices and LANs‚ but is now often used for Internet access. It enables a person with a wireless-enabled computer or personal digital assistant (PDA) to connect to the Internet when in proximity of an access point. Wireless Fidelity is the wireless
