Calcualte the `pH` at which an indicator with `pK_(b) = 4` changes colour.

What is PH at which an acid indicator with K_a = 1xx 10^(-5) changes colour when the indicator concentration is 1xx 10^(-3) M ?

pH at which an acidic indicator with K_("in")=1xx10^(-5) changes colour when the indicator is 1xx10^(-3) M is

pH at which a basic indicator with K_("in")=1xx10^(-10) changes colour when the indicator is xx10^(-2)M is

At what pH will a 10^(-3)M solution fo indicator with K_(b) = 10^(-10) changes colour?

At what pH will a 10 −4 M solution of an indicator with K b ​ =1×10 −11 change colour?

At what pH will a 10 −4 M solution of an indicator with K b ​ =1×10 −11 change colour?

Consider the following statements : Consider the following statements Both acids and bases change colour of all indicators If an indicator gives a colour change with an acid, it does not give a change with a base If an indicator changes colour with a base, it does not change colourwith an acid Change of colour in an acid and a base depends on the type of the indicator Which of these statements are correct?

Consider the following statements: (a) Both acids and bases change colour of all indicators. (b) If an indicator gives a colour change with an acid, it does not give a change with a base. (c) If an indicator changes colour with a base, it does not change colour with an acid. (d) Change of colour in an acid and a base depends on the type of the indicator. Which of these statements are correct?
