![]() This variation is due to the fact that the acidic pH of these drinks can cause hydrolysis of sugar upon storage, which can reduce their concentration. The variations in pH of the soft drinks showed the following trend: M2 > M7 > M5 > M1 > M3 > M4 and M6. The change is same for M3, M4, M6 and M7 is 3% while for M2 and M5 is 4%, and totally different for M1 which was 6%. Soft drinks show increase in pH during storage for M1 is 6%, M2 and M5 is 4%, M3, M4, M6 and M7 is 3%. ![]() ![]() The metal concentrations were determined by atomic absorption spectroscopy (AAS) and pH using glass electrode pH– meter (Jenway 3020 pH meter). ![]() The pH value of commonly consumed soft drinks (fanta, sprit, merinda, pepsi, etc.) in Nigeria was assessed based on their physiochemical properties (pH) variation and metal concentrations (Na, K, Mg, Mn, Pb, Ca, Fe, Cu and Zn). ![]()
