Penggunaan Fenolftalein<\/strong><\/h2>\n

1. Fenolftalein adalah asam organik lemah. Ini adalah kristal halus berwarna putih atau agak kekuningan pada suhu kamar. Tidak berbau dan tidak berasa. Ini hampir tidak larut dalam air tetapi mudah larut dalam alkohol (etanol) dan eter. Dilarutkan dalam larutan alkohol untuk membuat indikator asam-basa, tidak berwarna dalam larutan asam, merah dalam larutan alkali atau larutan karbonat logam alkali, tetapi jika dalam larutan alkali pekat akan menghasilkan trimetal yang tidak berwarna. Mengingat karakteristik ini, sering digunakan sebagai indikator titrasi asam-basa di laboratorium. Kisaran warna nilai PH adalah 8,2 \uff5e 10,0, dari tidak berwarna hingga merah. Ketika reagen fenolftalein diteteskan ke dalam air atau larutan asam netral, kekeruhan putih akan muncul. Hal ini karena alkohol mudah larut dalam air dan fenolftalein, yang hampir tidak larut dalam air, mengendap dalam reagen.<\/p>\n

2. Bahan Farmasi: Phenolphthalein digunakan sebagai pencahar ringan farmasi untuk sembelit yang biasa dan terus-menerus. Ini tersedia dalam bentuk tablet, supositoria dan bentuk sediaan lainnya, terutama di usus besar, melalui penguraian tubuh untuk membentuk garam natrium yang dapat larut, merangsang pleksus saraf di dinding usus, sehingga gerakan peristaltik meningkat dan meningkatkan buang air besar.
\n3. Sintesis organik: Fenolftalein juga digunakan dalam sintesis plastik, terutama sintesis polimer keton poliarylether keton diazanaphthone polyarylether keton. Polimer ini memiliki ketahanan panas yang baik, tahan air, tahan bahan kimia, tahan penuaan panas dan pengolahan dan pembentukan, terbuat dari serat, pelapis dan komposit yang banyak digunakan dalam peralatan listrik dan elektronik, mesin dan peralatan, transportasi, dirgantara, teknik energi atom dan militer dan bidang lainnya.<\/p>\n

4. Analisis kimia: Fenolftalein dapat digunakan sebagai endokrinator untuk penentuan keasaman kunci secara kolokal dan deteksi ion magnesium. Fenolftalein sebagai endokrinator dapat menunjukkan konsentrasi asam Cina. Dalam deteksi ion magnesium, fenolftalein dapat menunjukkan keberadaan dan konsentrasi ion magnesium.<\/p>\n

5. Jejak biokimia: Fenolftalein dapat digunakan sebagai pengenal untuk beberapa tes biokimia untuk mendeteksi ada atau tidaknya ciri-ciri, misalnya mendeteksi adanya reaksi enzim dan aktivitas metabolisme.<\/p>\n

6. Obat-obatan dan pigmen: Fenolftalein dapat dibuat sebagai senyawa sintetis untuk beberapa organofarmasi dan pigmen. Ini dapat digunakan sebagai persiapan untuk memberikan warna yang berbeda pada gulungan dan bahan lainnya.<\/p>\n
