Abstract: Glass electrodes respond slowly in dilute nearly neutral solutions (l= 0 1-1 mmol dm-3 pH 6-9) of either natural lake water or simple inorganic salts taking ~10 min to equilibrate irrespective of whether the solution is flowing or static Although buffer capacity and ionic strength influence the response they are not critical factors The transient effect is associated with low

What chemical compounds might be present in drinking water?

The sodium salt Na3P3O9 containing the cyclic P3O93− anion is formed when NaH2PO4 is heated to 600-640 C and the melt then maintained at 500 C High-temperature dehydration (800 C) above the melting temperature of NaH2PO4 (628 C) yields a liquid with very high relative molecular mass which gives slightly soluble solids of formula (NaPO3)n: Start of Equation nNaH2PO4 = (NaPO3)n

Salt flux is a mixture of sodium chloride (NaCl) and potassium chloride (KC1) with lower amounts of other compounds such as calcium fluoride (CaF2) [16 31-34] Salt flux melts at a slightly lower temperature than aluminum and therefore coats the metal before it melts in the furnace and reduces aluminum metal loss to oxidation Additives in salt flux also penetrate and break down previously
