請問這題酸鹼滴定要怎麼算 卡了很久還是想不出來 如果是當量點的話H+ OH-莫耳數不是相同嗎 這樣不是PH=PKa嗎

BA 48. Calculate the pH at the equivalent point in the titration of 40ml of 0.025M benzoic ↳ 苯甲酸 CH602 84+6+32 acid(Single proton acid) with 0.5M NaOH.

The technology is 16 on automated machines, which put down many thin layers of materials, such as plastic, metal and concrete, on top of each other to create objects in a bottom-up manner. Simple 17 the mechanism of the technology seems, it has been widely used in creating specialized items and delicate parts in the manufacture of a variety of industrial products, ranging from automobiles to medical devices. But now, some startups have been experimenting with the idea of building structures with the aid of 3D printing by making wise use of its inherent advantages. The employment of a 3D printing system can 18 reduce construction costs by up to 30 percent. In fact, parts of the costs cut down actually result from the removal of nearly all building waste in the constructing process, which can save up to three tons of carbon per home. 19 with the 3D printing technology, houses can be produced at two times the rate of traditional ways. The productivity of a standard 3D printing system is estimated to be roughly equivalent to 20 of 20 workers in several different fields combined. After all, machines, unlike humans, can work 24 hours a day nonstop. 0 16. 7 (A) sufficient (B) insistent (C) consequent (D) dependent Dcuso (B) but (C) while (D) though 130 hp 18.
