Three samples were made with the variation of Sulphuric acid concentration. Those were with 1 %, 1.5 % and 2 % Sulphuric acid. Three sample data are given in Table 02. The results show that the highest ethanol percentageis obtained with the sample of
2 % Sulphuric acid. The basic reason behind this is the higher concentration of Sulphuric acid the reducing sugar concentration in the solution also goes high. Graphical presentation of those data is given in Figure 02.
