Methyl orange is a commonly used dye in secondary school science studies. It is primarily used as a pH indicator in chemistry experiments. Methyl orange changes color in response to changes in acidity or alkalinity of a solution. It transitions from red in acidic solutions to yellow in basic solutions. This makes it particularly useful in acid-base titrations and pH determination experiments. Students can observe and interpret the color changes to determine the endpoint of a titration or the pH of a solution. Methyl orange's simplicity and effectiveness as a pH indicator make it a valuable tool for teaching acid-base concepts in secondary school education.

甲基橙是中學科學研究常用的染料。 它主要用作化學實驗中的pH指示劑。 甲基橙會隨著溶液酸性或鹼性的變化而改變顏色。 它在酸性溶液中從紅色轉變為鹼性溶液中的黃色。 這使得它在酸鹼滴定和 pH 測定實驗中特別有用。 學生可以觀察並解釋顏色變化,以確定滴定終點或溶液的 pH 值。 甲基橙作為 pH 指示劑的簡單性和有效性使其成為中學教育中酸鹼概念教學的寶貴工具。甲基橙是中學科學研究常用的染料。 它主要用作化學實驗中的pH指示劑。 甲基橙會隨著溶液酸性或鹼性的變化而改變顏色。 它在酸性溶液中從紅色轉變為鹼性溶液中的黃色。 這使得它在酸鹼滴定和 pH 測定實驗中特別有用。 學生可以觀察並解釋顏色變化,以確定滴定終點或溶液的 pH 值。 甲基橙作為 pH 指示劑的簡單性和有效性使其成為中學教育中酸鹼概念教學的寶貴工具。
