Qu\u2019est-ce qu\u2019un acide ?<\/h3>\n\n\n\n

Les acides, c\u2019est simple : ce sont des substances qui adorent les ions d\u2019hydrog\u00e8ne <\/strong>(H\u207a). Plus il y a d\u2019ions H\u207a, plus l\u2019acidit\u00e9 est forte.<\/strong> On mesure \u00e7a avec <\/strong>le fameux pH<\/strong><\/a>. \ud83d\uddd2\ufe0f<\/p>\n\n\n

Tu sais, ce truc qui va de 0 \u00e0 14 et qui mesure la concentration de l\u2019ion d\u2019hydrog\u00e8ne dans une solution. Si le pH est inf\u00e9rieur \u00e0 7, c\u2019est acide\u202f!<\/strong> Comme le citron ! \ud83c\udf4b<\/p>\n\n\n\n
