उत्तर
Alkalis have a pH greater than 7.
Explanation:
Alkalis have a pH greater than 7 because the pH scale measures the concentration of hydrogen ions, with 7 being neutral. Alkalis release hydroxide ions in water, which decrease the concentration of hydrogen ions and push the pH above the neutral midpoint. Consequently, higher numbers on the 0-14 scale indicate much stronger alkaline properties.
