What is the correct pH value of weak and strong alkalis?
2020年5月13日 · Ammonia solution with a pH of 11.1 is a weak alkali and that's why it shows much lower conductivity of 0.50 US/cm. However at p. 147 it's written that . a solution with a pH of 10 is a strong alkali. So either the correlation of pH with conductivity is incorrect or the statement that ammonia solution with a pH of 11.1 is a weak Alkali is wrong.
