yellow. The expression to this reaction is presented as BrO3-(aq) + 6I-(aq) + 6H+(aq) → Br-(aq) + 3I2(aq) + 3H2O and due to the excess amount of I-‚ I2 reacts with I- to form I3- (I- (aq) + I2 (aq) ↔ I3-). Add 5mL of starch indicator. The starch indicator with react with I3- in the solution and turn its color to blue. The I3- formed then reacts with S2O32- (thiosulfate) and produces S4O62- (tetrathionate) and three I1-. Titrate the solution until the blue color disappears. Then calculate the concentration

The solution should be a dark yellow to redbrown from the presence of I3 - complex. 4. Titrate the iodine. Rinse the buret with distilled water and then three times with small portions of your 0.10 M sodium thiosulfate solution. Then‚ fill up the buret with the 0.10 M sodium thiosulfate solution.

Recent Development in Computer Technology Tablet Computer: A tablet computer‚ or simply tablet‚ is a complete mobile computer‚ larger than a mobile phone or personal digital assistant‚ integrated into a flat touch screen and primarily operated by touching the screen. It often uses an onscreen virtual keyboard or a digital pen rather than a physical keyboard. Electrical devices with data input and output on a flat information display have existed as early as 1888. Throughout the 20th century many

algebraic sum of the currents entering a node is equal to zero. 2. What is the equation for the total current in a parallel circuit? It= I1+I2+I3…. 3. Determine the total current in the following nodes. 1) It= 2mA+4mA+6mA= 0.012x10^-3=12mA 2) I + I1+I3= I2 I= 2mA+4mA= 1mA I= 1mA- 6mA I= -5mA 4. Determine the total current in the following circuit. It= I1+I2+I3= 10mA+20mA+40mA= 0.07 x 10^-3= 70mA 5. If VS = 10 V in the circuit above‚ what are the following voltages? R1= V/I= 10V/10mA= 1000

measured by changes in concentrations per unit time. For example‚ in the following reaction (all species are in aqueous solution): S2O82- + 3 I- → 2 SO42- + I3- (1) the reaction rate could be determined by following a decrease in the concentrations of reactants (S2O82- or I- ) or by the increase in the concentration of the products (SO42- or I3-). However‚ we need to recognize that these rates of change would all produce different numbers. [ ] [] [ ] [] 2Δ S2O2Δ I8 3 1Δ I
