information‚ Sales and Marketing must clearly define the exact requirements of the customer to ensure they are incorporated into the specification. There is no easy way of solving the design problem and transforming the specification into a design solution. Whatever the system whereby the initial specification is produced‚ the method used to translate it into the final design always follows a basic pattern and can be summarised in the following five steps. 1. Identification of the problem.

higher concentration of solute ( meaning‚ a lower concentration of water) . In osmosis different concentrations of solutes are compared. A solution that has equal concentrations of solute is isotonic. A solution with a higher concentration of solutes is hypertonic and one with less concentration of solutes is hypotonic. “The term osmolarity is

CHEM 3411‚ Fall 2010 Solution Set 5 In this solution set‚ an underline is used to show the last significant digit of numbers. For instance in x = 2.51693 the 2‚5‚1‚ and 6 are all significant. Digits to the right of the underlined digit‚ the 9 & 3 in the example‚ are not significant and would be rounded off at the end of calculations. Carrying these extra digits for intermediate values in calculations reduces rounding errors and ensures we get the same answer regardless of the order of arithmetic

properties In liquid solutions‚ particles are close together and the solute molecules or ions disrupt intermolecular forces between the solvent molecules‚ causing changes in those properties of the solvent that depend in intermolecular attraction. For example‚ the freezing point of a solution is lower than that of the of the pure solvent and the boiling point is higher. Colligative properties of solution are those that depend on the concentration of solute particles in the solution‚ regardless of what

carbonate solution and pH indicator phenolphthalein will be added ahead of lipase enzyme; when the pH is below 8.2‚ phenolphthalein will turn from pink to colourless. Sodium carbonate solution is added in order to turn the solution alkaline and the indicator pink then back to colourless after lipase is added to catalyse the chemical reaction and speed up the breakdown of lipids into fatty acid in the milk. Fatty acid produced then is going to neutralise the solution with sodium carbonate solution added
