Titration is a method used to help determine the concentration of an unknown solution (the analyte) by using a solution of known concentration (the titrant).1 In medicine‚ titration helps doctors determine unknown concentrations of substances in the blood or urine‚ and it is useful in determining the proper dosage of medication. Titration can determine fat and water contents‚ and unknown concentrations of vitamins. With food‚ titration can be used to determine whether cheese or wine is adequately

SOLUTION AND CONCENTRATION A solution is a homogeneous mixture‚ made up of a solute dissolved in a solvent. Ex. In a water (aqueous) solution of sodium chloride‚ the sodium chloride is the solute and the water is the solvent. Solute – the component that is dissolved or is the least abundant component in the solution. Ex. Sugar‚ salt Solvent – the dissolving agent or the most abundant component in the solution. Ex. Water Common Types of Solution State of Solution State of Solute

Lab Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isotonic solution is a concentration and solution that is the same amount. Hypothesis question: What will happen if you put a potato in hypertonic solution? What will happen if you put a potato in hypotonic solution? What will happen if you put a potato in isotonic solution? Hypothesis statement: If you put sugar

Conductivity Solutions Abstract: We produced conductivity tests in water and other various solutions with a computer faced Conductivity Probe using the unit of microsiemens per centimeter (uS/cm) to find out which solutions had a high conductivity and which solutions had a low conductivity. Many different solutions vary in conductivity due to the ratio of ions. Different levels of ions have an impact on conductivity because of the different charges and different types of bonds. Conductivity is

Solution Focused Therapy Solution Focused Therapies are future oriented and goal directed therapies that focuses on solutions and what the client wants to change in their life‚ rather than dwelling on the why and the history of the problem that brought them to therapy (De Shazer‚ 1985). Solution focused therapies are brief forms of therapy that is applicable to diverse populations‚ making it the therapy of choice in a variety of settings (Corcoran & Pillai‚ 2009).

Question # 1 What business is LCI in? What are the key success factors? How operations can contribute? LCI BUSINESS: LCI was founded in 1994 by Mr. Sheikh Ubaidullah‚ a Former Chairman of Pakistan Cycle Cooperative Society Limited. LCI is located at Ferozpur Road‚ eighteen miles south of Lahore Pakistan. LCI marketed its bicycles under the brand name of Leader bicycles. LCI was in bad shape and financially bankrupt ‚ all shops run by one supervisors ‚ its production was practically zero when Managing

water and‚ more recently‚ generation of electricity. Contemporary electricity-generating versions are referred to as wind turbines. In the context of our country‚ where we continually suffer from load shedding‚ windmill sounds like a creative solution. Although the idea of setting up windmills here is a new idea‚ the concept is lot older. We have the “Kaptai Dam” in “Karnafuli” where we use the force of water to produce electricity which is based on the same principle.

Applied Mathematics 1 Trigonometric Ratios with solutions O A O cos θ = tan θ = H H A where O = opposite‚ A = adjacent and H = hypotenuse. sin θ = 1. The angle of elevation of the top of a tree from a point on the ground 10m from the base of the tree is 28◦ . What is the height of the tree? Solution We need to find the height of tree which is opposite an angle of 28◦ .Thus O tan θ = A O = A tan θ height of tree = 10 × tan 28◦ =⇒ height of tree = 5.3m 1d.p. 2. Using a surveying
