The ionisation constant of an acid base indicator (a weak acid) is `1.0 xx 10^(-6)`. The ionised form of the indicator is red and unionised form is blue. The p`H` change required to alter the colour of indicator form `80%` red is

The ionisation constant of an acid base indicator (a weak acid) is 1.0 xx 10^(-6) . The ionised form of the indicator is red and unionised form is blue. The p H change required to alter the colour of indicator from 80% red to 20% red is

The ionization constant of an acid-base indicator (a weak acid) is 1.0×10^(−6) . The ionized form of the indicator is red whereas the unionized form is blue. The pH change required to alter the colour of the indicator from 80% blue to 80% red is:

An acid base indicator has K_(a)=1.0xx10^(-5) the acid form of the indicator is red and the bais form is blue. Calculate the pH change required to change the colour of the indicator from 80% red to 80% blue.

An acid-base indicator has a K_(a) = 3.0 xx 10^(-5) . The acid form of the indicator is red and the basic form is blue. Then

An acid-base indicator has a K_(a) = 3.0 xx 10^(-5) . The acid form of the indicator is red and the basic form is blue. Then

An acid base indicator has K_(a)=1.0xx10^(-5) the acid form of the indicator is red and the basic form is blue. Calculate the pH change required to change the colour of the indicator from 80% red to 80% blue.

An acid -base indicator has a Ka of 3.0 xx 10^(-5) The acid form of the indicator is red and the basic form is blue. Then

An acid-base indicator has K_(a) = 3.0 xx 10^(-5) . The acid form of the indicator is red and the basic form is blue. Then:
