Explain why pH = pKa at one half the volume need to reach the equivalence point for the titration of a weak acid with a strong base.

Which is mostly likely why many scientists reject the cold fusion theory

H2so4(aq) + mg(s)—> mgso4(aq) +h2(g) which substance is the acid in the reaction?

How can a give a full method for the experiment of separating sand from water by filtration? 1-materials 2-steps 3-conclusion also for water and salt separated by the evaporation or distillation process
