in the hand of contractors. As a civil engineer, it’s our duty to complete the project within the time and specified budget. 1.2 AIMS • To analyze & determine the causes and effect of delay and cost overrun of the project to compute the proper solution
Antacid Objective: In this experiment, you will standardize a solution of base using the analytical technique known as titration. Using this standardized solution, you will determine the acid neutralizing power of a commercially available antacid tablet. Introduction An understanding of the properties of acids and bases is an essential part of understanding chemical reactions (see Tro, pp 167-171). In aqueous solutions, a compound that produces H+ ions upon dissolution is termed an acid. A compound that

Fresh tea leaves were fermented following a rotatable
plastic waste which directly destroying the environment. Such materials cannot be degrading easily, expensive for the recycling and causes contamination to food stuffs. One of the alternative ways to solve this problem is biodegradable films.Recently studies on biodegradable packaging films for the replacement of synthetic polymer-based food packaging materials have increased (Abdorreza, Cheng, & Karim, 2011). Biodegradable packaging materials can be degraded into water, carbon dioxide, and inorganic
important in different technologies among which is metallurgy and metal corrosion. An example is the study by Hamilton and woods (Hamilton and Woods, 1981) who studied the products of sulphur oxidation of pyrite and pyrrhotite. In the floatation of sulphide minerals and base metal oxides, alkali sulphides have been widely used for a long time (Buswell and Nicol, 2002) which lead to extensive study of sulphur chemistry. In natural gas and crude oil industries, the effects of corrosion that sulphide

pH of solutions using the pH meter and by the Henderson Hasselbalch equation, which after comparison is made between the values. pH meter was used to measure the pH of the solutions and also the titration curve was established from the recordings of the pH and of volume of the base which was the NaOH. Factors that affect the buffer capacity were then evaluated and explained why they affect the buffer capacity. Calculations were done in results as determining the volumes and pH of the solution using
