Chhattisgarh Board Solutions for Chapter: Acids, Bases and Salts, Exercise 6: Questions

Are ${\mathrm{H}}^{+}$ ions present in basic solutions? If yes, then why is the solution basic? 

You have two solutions "$\mathrm{A}$" and "$\mathrm{B}$" in water. The pH value of solution "$\mathrm{A}$" is $6$ and that of "$\mathrm{B}$" is $8$. Which solution will have a higher concentration of hydrogen ions? Which one of the solutions is acidic and which is basic? 

When Julie tested solutions $"\mathrm{A}", "\mathrm{B}", "\mathrm{C}", "\mathrm{D}"$ and $"\mathrm{E}"$" using a universal indicator, she got $\mathrm{pH}$ values of $9,7,1,13$ and $6$ respectively. On this basis can you tell which solution- 

(a) Is a weak acid 

(b) Is a weak base 

(c) Is a strong acid 

(d) Is a strong base 

(e) Is neutral.
 

When Julie tested solutions$"\mathrm{A}", "\mathrm{B}", "\mathrm{C}", "\mathrm{D}" \mathrm{and} "\mathrm{E}"$ using a universal indicator, she got $\mathrm{pH}$ values of  $9,7,1,13 \mathrm{and} 6$ respectively. Arrange the solutions in increasing order of hydrogen ion concentration.
