Volumetric Analysis

The pink color of the dilute MnO4- solution indicates the end of the reaction. This is known as the "end point" or equivalence point of the titration.
3. Heat each solution containing the iron sample almost to boiling. SnCl2 solution should be added drop wise taking care such that the yellow Fe(III) color just disappears. Then add only 2 drops excess of SnCl2 solution. The solution is cooled by placing the outside edge under running cold water until held, ...

Means of detecting the end point of the reaction between the standard and test solutions. Usually an indicator is used however in redox titrations, the oxidising agents are self indicators which means an indicator is not needed.
In the above reduction half-reaction, manganese has undergone a decrease in oxidation number from +7 to +2…

Data Analysis and Interpretation
Using the value 0.05 level of significance, F-statistics, and an Analysis of variance (ANOVA) test, the df num value is k-1, or 2 -1, or 1 and the df den value is T-k, or 150 - 2, or 148. So, with = 0.05, the critical value of F in this analysis of variance test was F0.05 (1, 148) = 253. Since computed F (FC) is less than Tabulated F (FT), Ho is accepted, which states that the British consumers' perception of "Rioja" wine attributes is affected by the image factors of "La Rioja" origin.

Gene therapy, integrating vectors carrying therapeutic transgene sequences offers the potential for a permanent cure of genetic diseases by stable vector insertion into the patients chromosomes (1). However there are some reports indicating occurrence of tumors at later stage in transgenic animal and that's why it is important to know probability of non specific integration of this transgene and its effect on cellular homeostasis. As per the present understanding the integration is semi-random in nature and having partial preference towards sequences in or near the coding regions of expressed...
