Solution pretreatments on enzymatic hydrolysis of hazelnut shells emir zafer ho g n with an alkaline solution and then with lhw pretreatment each method had a different effect on the pre-processing of the biomass. Investigating effect of temperature on the activity of lipase an alkaline solution of milk, lipase and phenolphthalein will change from pink to colourless as the fat in milk is broken down to form this investigation could be carried out as a demonstration at two different temperatures. Chloride and hydroxide ions have different effects on the corrosion behaviour of copper alkaline solutions, with the outer cu(ii) precipitated layer responsible for passivation although the behaviour in neutral or acidic chloride solutions or in chloride-free alkaline.
Indicators and the ph scale when an acid is dissolved in water we get an acidic solution, and alkalis make alkaline solutions if a solution is neither acidic nor alkaline we call it neutral universal indicator is a mixture of several different indicators.
