有關有機化學實驗的問題(英文)20點

If 1.0 liter of an aqueous solution is sufficiently basic that 50% of 1.0g of dissolved benzoic acid is in ionic form,approximately what percent of 1.0g of 2-naphthol in the same solution will be ionized?

請問這是什麼意思?

要如何解題?

    1.0升的鹼足夠讓1.0g的苯甲酸50%變為離子,同樣的鹼能讓1.0g 的 2-naphthol多少變為離子?

    2-naphthol也是只有一個可以拔的H,所以求出相同的mol數就OK了.

    benzoic acid 分子量122

    2-naphthol就是2-Hydroxynaphthalene分子量144
