酸反应与盐
Acid Reactions & Salts
描述酸与金属、碱(中和反应)以及金属氧化物/氢氧化物的反应,写出反应的文字化学方程式,并指出每种反应生成的盐。
Describe and write word equations for the reactions of acids with metals, alkalis (neutralisation), and metal oxides/hydroxides, identifying the salt produced in each case
学习证据 / Evidence
- 会写出文字化学方程式:酸 + 金属 → 盐 + 氢气;酸 + 碱 → 盐 + 水;酸 + 金属氧化物 → 盐 + 水。
- 能根据给定的酸和碱说出生成的盐(例如:盐酸 + 氢氧化钠 → 氯化钠)。
- 能描述氢气的检验方法(发出尖锐爆鸣声)。
- 能解释中和反应的含义,并举出实际例子(消化药片、处理酸性土壤)。
- Writes word equations for: acid + metal → salt + hydrogen; acid + alkali → salt + water; acid + metal oxide → salt + water
- Names the salt formed from a given acid and base (e.g. hydrochloric acid + sodium hydroxide → sodium chloride)
- Describes the test for hydrogen gas (squeaky pop)
- Explains what neutralisation means and gives a practical example (indigestion tablets, treating acidic soil)
评估问题 / Assessment
如果{{name}}被问到消化药片如何缓解胃酸,ta能否解释其中发生的化学反应类型,并写出一个简单的文字化学方程式?
If {{name}} was asked how an indigestion tablet works to relieve stomach acid, could they explain what type of chemical reaction is happening and write a simple word equation for it?
