想請問版上的化學神手K2B4O7(四硼酸鉀)的當量數(N)是多少基本資料:http://ppt.cc/HgGc 因為跟傳統HCl(N=1) H2SO4(N=2)常見的解離方式不同不知道它到底是怎麼解離的...所以不確定當量是多少... 最近在做實驗要配0.5N的K2B4O7 本來是猜當量數N=2下去配置溶液結果實驗失敗了... 怕是當量數算錯導致溶液配錯... 第一位和第二位回答的版友願意致上100P(稅前)作為答謝謝謝大家的幫忙了~~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.116.193.111 ※ ufogirl:轉錄至看板 Chemistry 08/24 11:16
