A universal indicator is a solution which undergoes several color changes over a wide range of pH's. The color is used to "indicate" pH directly. Universal indicators are usually mixtures of several indicators. The easiest universal indicator to prepare is red cabbage juice. Stew red cabbage in water and pour off the water for use as an indicator solution. The pigment in red cabbage juice is anthocyanin, which changes color from red in acid solution to purplish to green in mildly alkaline solution to yellow in very alkaline solution. The color changes for red cabbage juice are shown to the right. read less

As IIT & board exams are coming near , students you are free ask any doubt in PCM boards or IIT/BITSAT . I completely understand the pressure , anxiety at this time. But maintain calm at this time & be happy .Don't take any stress and just keep on studying with the flow . Truly speaking the person who is studying till the end with happiness only crack these competitive exams easily. Many students leave studying in the last due to tension or piling of massive course. One suggestion for these students is, whatever will going to happen in future is not in your hands , what really in your hands is --> this time !! so just give your best in this time and forget everything else. Don't feel that others have studied more than me, or they have been studying from 2 years or starting , because anything can happen in the last , this is a true fact !! It's about your processor not Harddisk meaning it's about how your brain run at that time in the exams , not specifically about how much you have stored. I myself have seen many people who have got very good ranks by just studying properly in last two months over those students who have been studying for 2 years continously . So remain motivated and give whatever you have to your studies . But very important thing remain happy and enjoy studies. I will be telling other tips & tricks to complete maximum portion in the last in less time . Keep tuned to my future posts.
As a chance to prove yourself and evaluated by a traditional way to the student. Student should not fear but make .

I was enrolled to a coaching for 11th and 12th standard. Due to my low performance in JEE advanced I want to give 1 more year to prep. I have all the study material. I am planning to just solve that and join test series. But the problem is how to get my doubts cleared? And will this strategy work?
you can look out for online tutors who can clear your doubts. Also there are many online forums available that can help you with the same. Look out for tricks that are available on Youtube. you can also opt for online test series.
