How does the pH of an acid solutoin change when it is diluted?

Ph of an acidic solution is:

How does the self inductance of an air coil change, when the number of turns in the coil is decreased?

How does the self inductance of an air coil change, when an iron rod is introduced in the coil?

Does the nature of a vector change when it is multiplied by a scalar?

How does the focal length of a glass lens change when blue light is replaced by red light. Give reasons.

How will the pH of brine be affected when it is electrolysed?

Solution of a weak acid and its anion (that is,its conjugate base) or of a base and its common cation are buffered. When we add a small amount of acid or base to any one of the, the pH of solution change very little. pH of buffer solution can be computed as for acidic buffer : pH=pK_(a)+ log.(["Conjugate base"])/(["Acid"]) for basic buffer : pOH=pK_(b)+log.(["Conjugate acid"])/([Base]) It is generly accepted that a has useful buffer cpacity (pH change resisting power) provided that the value of [salt or conjugate base] /[acid] for acidic buffer lies within the range of 1 : 10 to 1. Buffer capacity is maximum when [conjugate base] = [acid] Calculater the pH of a solution made by adding 0.01 mole of HCl in 100 mL of a solution which is 0.2 M in NH_(3)(pK_(b)=4.74) and 0.3 M in NH_(4)^(+) : (Assuming no change in volume )

How does the junction width change when a p-n junction is forward biased?
