can anyone give me some problems in the lesson electricity and magnetic field of electric current except the problems which is in the book
What is the Difference between Alkaline and basic?
what is pH paper exactly(full form)????
what is the ph of dil. sodium bicarbonate????
what is pH paper
A student adds a few drops of universal indicator to a solution and observes colour changes to orange. The solution would be : (a) strong acid (b) strong base (c) weak acid (d) weak base
What is the difference between pH paper and universal indicator ?
A student has four samples A, B,C and D containing dil.HCl, aq KCl, dil.NaOH, and distilled water respectively. The solutions with equal pH are:
(a) A and B
(b) B and C
(c) C and D
(d) B and D
What will be the colour of the pH paper when we wil drop a liquid called Dilute Hydrochloric Acid , Dilute NaOH solution , Dilute Ethanoic Acid Solution ,Lemon Juicce, Water ,Dilute Sodium Bicarboate Solution. And pH paper value also.
