磷酸銀呈黃綠色 已有3人參與
|
| 如題。硝酸銀與磷酸氫二鈉反應(yīng),總感覺生成的磷酸銀是換綠色,這是為什么呢?小伙伴們求解答 |
磷酸銀相關(guān) |

|
因為磷酸銀光敏性較好,在反應(yīng)過程中盡量避光進(jìn)行,在太陽光照射下,幾小時內(nèi)磷酸銀就會變色。 Ag3PO4 was synthesized by the ion-exchange method as follows. AgNO3 powder (0.075 mol) was dissolved in 500 mL of deionized H2O. Then, 0.1 mol/L of Na2HPO4 (250 mL) aqueous solution was added in drops into the above solution under continuous stirring until yellow precipitates were formed. Finally, the mixture was washed with distilled water and dried at 60 °C in air overnight.我用這個方法合成的是亮黃色的,催化效果較好,你可以試試。 另外,請問你知道磷酸銀的零電荷點(The pH of the point of zero charge (pHPZC))是多少嗎? |
