EXPERIMENT 2: SOLUTION PREPARATION AND STANDARDIZATION Submitted by Iris Olaso ______________________________________________________________________________ INTRODUCTION Generally‚ there are two ways in preparing a solution‚ one is by dissolving a weighed amount of solid in a required solvent and the other is by dilution of a concentrated solution into the desired concentration. In diluting concentrated solution‚ the concentration of the diluted solution can be determined by standardization

Chapter 5: Cost Behavior: Analysis and Use As we shall see in later chapters‚ the ability to predict how costs respond to changes in activity is critical for making decisions‚ controlling operations‚ and evaluating performance. Three major classifications of costs were discussed in this chapter—variable‚ fixed‚ and mixed. Mixed costs consist of variable and fixed elements and can be expressed in equation form as Y = a + bX‚ where X is the activity‚ Y is the cost‚ a is the fixed cost element‚ and

Conqueror had defeated Harold at the Battle of Hastings in 1066‚ an even bigger challenge had presented itself. William was now outnumbered in a land he had very little knowledge of‚ and would face several rebellions in the first decade of his reign. William was aware of this challenge‚ building castles in towns which presented any threat as a symbol of his power. Despite these measures‚ it would take William almost a decade‚ until 1075 to gain full control of England‚ which he did so due to several different

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

CAT 2007 Solutions Section I 1. Note that the price of Darjeeling tea remains constant after the 100th day (n=100). If the prices of the two varieties of tea become equal before n = 100‚ then 100 + 0.1n = 89 + 0.15n ∴ n = 220‚ which is not possible. (Since n has been assumed to be less than 100) ∴ The prices of the two varieties will be equal after n = 100‚ i.e.‚ when the price of Darjeeling tea = 100 + 0.1 × 100 = 110 ∴ 89 + 0.15n = 110 ∴ n = 140 2007 is not a leap year.

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
