Measurement of KLa in a bioreactor can be carried out by sodium sulfite oxidation method, that is, based on the oxidation of sodium sulfite to sodium sulfate in the presence of a catalyst (Cu++ or Co++). In a typical experiment, a laboratory fermenter was filled with 5 liter of 0.5 M sodium sulfite solution containing 0.003 M Cu++ ions and the air was sparged in. After 10 min, the air flow was stopped and a 10 mL sample was taken and titrated. The concentration of sodium sulfite in the sample was found to be 0.20 M. The oxygen uptake rate for this aerated system will work out to be

With reference to street-lighting, how do sodium lamps differ from LED lamps? 1. Sodium lamps produce light in 360 degrees but it is not so in the case of LED lamps. 2. As street lights, sodium lamps have a longer life span than LED lamps. 3. The spectrum of visible light from sodium lamps is almost monochromatic while LED lamps offer significant colour advantages in street lighting. Select the correct answer using the code given below.  
There are two beakers with the first containing sodium hydroxide solution and the other beaker has twice the quantity of water. To prepare a solution, 60 ml of sodium hydroxide is added to the water beaker. Three fourth of the prepared solution is again added to the first beaker. After this the first beaker has 3.5 times the solution in the water beaker. How much was the initial amount of sodium hydroxide?
