酸，可以帮助消化 硫酸作_干__燥_剂____
3.浓硫酸 (1)浓硫酸的特性 ①吸水性：浓硫酸放置在空气中会吸水，溶液的质量会增 加，溶质质量分数将减少。浓硫酸可作干燥剂，但不能干 燥氨气(NH3)等碱性气体。
②腐蚀性(脱水性)：浓硫酸能夺取纸张、木材、布料、皮 肤(都是由碳、氢、氧等元素组成的化合物)里的 H、O 原 子(按照个数比 2∶1 的比例)，生成黑色的炭(这种作用通常 叫做脱水作用)。有强烈的腐蚀性，如果不慎将浓硫酸沾在 皮肤或衣服上，应立即用大量水冲洗，然后再涂上 3%～ 5%的碳酸氢钠溶液。

人这一辈子说长不长，说短也不短。既 然沿途 有着绚 美的风 景，我 们又何 必风雨 兼程脚 不停息 ？既然 眼前便 有旖旎 的风情 ，又何 必对未 知的前 方魂牵 梦萦？ 生活中 ，其实 我们每 个人都 有目标 ，并且 我们的 奋斗， 都是为 了能离 它更近 。奋斗 努力， 快步走 行，无 可厚非 ，但是 我想， 人生在 路上行 走，本 应该走 走停停 ，该歇 的则歇 一歇， 该停的 则停一 停，在 生活一 直往前 走的同 时，适 时的放 慢脚步 ，看看 你的身 边，看 看你的 周围， 欣赏一 下沿途 的美丽 风景， 也许里 面就有 会你想 要的东 西。不 要为了 追求物 质财富 ，不要 忙于到 达目的 地，只 顾疲于 奔跑， 而错过 了身边 美丽的 风景， 不要让 你已拥 有的很 多东西 在手中 悄悄的 流失， 失去对 它的珍 惜，更 不要怨 天怨地 怨人怨 己，抱 怨自己 的人生 磕磕绊 绊，不 如人意 。要知 道很多 时候， 当在你 盲目地 追求着 你的目 标后， 当你在 怨天怨 地怨人 怨己时 ，回过 头来看 时，可 能会发 现：许 多的美 丽和幸 福，原 来就在 你路途 的景色 里！

计较的太多就成了一种羁绊，迷失的太久便成了一种痛苦。过多的在乎会减少人生的乐趣，看淡了一切也就多了生命的释然。 一个人的价值，不体现在与别人相同的东西上，而体现在与别人不同的东西上。 得到的分是我努力的，扣掉的分是你遗传的！ 做最好的今天，回顾最好的昨天，迎接最美好的明天。 一个人的度量是一种精神力量，是一股强大的文明力量。 一份耕耘，一份收获，付出就有回报永不遭遇过失败，因我所碰到的都是暂时的挫折。 勇敢地接受挑战，不断地超越自我，这样才能发出你的无限潜能。 你可以用爱得到全世界，你也可以用恨失去全世界。
