style="text-indent:25px">測(cè)量超純水的pH值需要特殊的條件有哪些？蘇州埃英環(huán)?？萍加邢薰拘【幗榻B，由于性質(zhì)比較特別，超純水被稱為世界上比較強(qiáng)力的溶劑。水的化學(xué)式是一個(gè)氧分子加兩個(gè)氫原子，無色無味。由于純水能夠溶解任何接觸到物質(zhì)，因此它的純度是不可能保持的。由于超純水沒有任何緩沖能力（即在溶解其他物質(zhì)的同時(shí)保持自身的pH值），因此比較微小的污染也會(huì)改變它的pH值。純水是一種優(yōu)良的絕緣體，因此在測(cè)量pH值的時(shí)候很難讓pH計(jì)的測(cè)量電極和參比電極之間導(dǎo)通。這樣在測(cè)量用的電極電路中產(chǎn)生極高的電阻，會(huì)使得測(cè)量的電信號(hào)噪聲變大，電極的反應(yīng)變慢，并產(chǎn)生靜電雙電層。這種靜電雙電層在純水流經(jīng)塑料管路時(shí)很常見，它產(chǎn)生的電場(chǎng)會(huì)使得測(cè)量得到的電阻比實(shí)際值要大，這樣測(cè)量得到的pH數(shù)值是錯(cuò)誤的。超純水的用途：電子、電力、電鍍、照明電器、實(shí)驗(yàn)室。浙江超純?nèi)ルx子水生產(chǎn)企業(yè)</p><p
