POLYVINYL ALCOHOL (PVA)
a 5% solution of polyvinyl alcohol exhibits a pH in the range of 5.0 to 6.5. Polyvinyl alcohol has a melting point of 180 to 190°C. It has a molecular weight of between 26,300 and 30,000, and a degree of hydrolysis of 86.5 to 89%. 3 Manufacturing The primary raw material used in the manufacture of polyvinyl alcohol is vinyl acetate monomer. It is

An iodine / thiosulfate titration
mccscience.yolasite.comThe iodine solution, which is a golden-brown colour, can be titrated against sodium thiosulfate solution. The sodium thiosulfate solution is placed in the burette and, as it is added to the conical flask, it reacts with the iodine and the colour of the solution fades. When it reaches a
IODINE CLOCK REACTION KINETICS
alpha.chem.umb.eduIodine Clock 6 o Thiosulfate molarity drops from [S2O3 2-]i to zero. o The I2 moles per liter consumed is [S2O3 2-]i /2 (see the balancing coefficients in Reaction 2). o The I2 consumed in Reaction 2 is produced in Reaction 1. o For each I2 mole produced, a mole of H2O2 is consumed (see balancing coefficients in Reaction 1). o Thus the H2O2 loss, Δ[H2O2], is [S2O3
