You have two solutions, $A$ and $B$. The $pH$ of solution $A$ is $6$ and $pH$ of solution $B$ is $8$. Which solution has more hydrogen ion concentration Which of this is acidic and which one is basic?
A $pH$ value of less than $7$ indicates an acidic solution, while greater than $7$ indicates a basic solution. Therefore, the solution with $pH =6$ is acidic and has more hydrogen ion concentration than the solution of $pH =8$ which is basic.
What is the common name of the compound $CaOCl_2$ ?
How is the concentration of hydroxide ions $(OH^-)$ affected when excess base is dissolved in a solution of sodium hydroxide ?
Why does an aqueous solution of an acid conduct electricity?
Five solutions $A,\,B,\,C,\,D$ and $E$ when tested with universal indicator showed $pH$ as $4,\,1,\,11,\,7$ and $9$, respectively. Which solution is
$(a)$ neutral ?
$(b)$ strongly alkaline ?
$(c)$ strongly acidic ?
$(d)$ weakly acidic ?
$(e)$ weakly alkaline ?
Arrange the $pH$ in increasing order of hydrogen-ion concentration.
Why do $HCl$, $HNO_3$, etc., show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character ?
