which studies ratios of lead to iodine. Precipitation reactions occur when oppositely charged ions attract and form an insoluble ionic solid. This experiment examines the precipitation reaction between lead (II) nitrate‚ Pb(NO3)2‚ and potassium iodide‚ KI. Both are dissolved in water and the reaction between these solutes will produce a water insoluble yellow solid referred to as the precipitate. Any substance with solubility less than 0.01 mol/L is considered insoluble. The formula of the insoluble

USP: Ariel has a USP of “Aik dhulai mukammal safai” which can be questioned but then again this positioning has been used by another well known brand from Colgate Palmolive Express which says“ Aik dhulai 65 rupee ki bachat ke sath” diverting the whole market from Ariel to Express. Brand Promise: It is a common observation that no detergent can clean the stains in the first go rather it takes atleast 2 times or 2 spins in washing machine to take out stains therefore

= KP + KI KD s 2 + KP s + KI + KD s = s s where KP = Proportional gain‚ KI = Integral gain and KD = Derivative gain. PID Controller structure In this tutorial‚ we assume the controller is used in a closed-loop unity feedback system. The variable e denotes the tracking error‚ which is sent to the PID controller. The control signal u from the controller to the plant is equal to the proportional gain (KP ) times the magnitude of the error plus the integral gain (KI ) times the

using the Arrhenius Equation. The experiment will go as follows: Into a conical flask put 15cm3 of distilled water and add 2cm3 of [X]moldm-3 potassium iodide (KI) solution and 1cm3 of 2moldm-3 sulphuric acid. Then add to this 2.5cm3 of 5vol (0.42moldm-3) hydrogen peroxide (H2O2). For the second part of my investigation‚ the KI solution will remain a constant 0.3moldm-3 and the H2O2 solution will vary.

reaction: Pb(NO3)2 + 2KI 2K(NO3)+ PbI2 1 mole of Pb(NO3)2 react with 2 moles of KI. Molecular mass of Pb(NO3)2: 207.19 + (14.01+16x3)x2 = 331.21m.m.u. Molecular mass of KI: 39.10+126.90 = 166m.m.u. Number of moles of Pb(NO3)2: 1.01g/331.21m.m.u. = 0.00305 mol (rounded). Number of moles of KI: 0.8g/166m.m.u. = 0.0048 mol (rounded). There is only 0.0048 moles of KI‚ therefore the limiting reagent is KI. Molecular mass of PbI2: 207.19 + 126.90x2 = 460.99m.m.u. Number of moles of PbI2:
