This is often indicated by a color change, for example by adding a few drop of phenolphthalein, a commonly used acid‑base indicator, which changes from pink in alkali to colorless in acid. 3. Calculate the Molarity Use the titration formula. If the titrant and analyte have a 1:1 mole...

Chemists sometimes use titration to determine the alkalinity of an unknown substance. The term "alkalinity" refers to the degree to which a substance is basic—the opposite of acidic. To titrate, you add a substance with a known [H+] concentration—or pH—to the unknown solution one drop at...
在生活中，我们（ ）常有两方面的原因，一则是缺乏自信，担心遭到别人的拒绝，伤害了自己的自尊。二则是很多人对于人际关系存在误解，如“先同别人打招呼，就是低人一等”，“那些善于交往的人都左右逢源，显得世故和圆滑”等。
