The used chemicals were hydrochloric acid, nitric acid, and lactic acid from Scharlau (Scharlab S.L., Spain), and iron nitrate, ascorbic acid, and 70% ethanol (Sigma Aldrich, Stockholm, Sweden). The deionized water was generated by Millipore Milli‐Q plus ultrapure water system (Millipore, Solna, Sweden). The four yeast extracts (YE1 to YE4) used for the baking studies were as follows: YE1 (Acros organics from Fisher Scientific, UK), YE2 (Bacto yeast extract from Difco Laboratories, UK), YE3 (Oxoid yeast extract from Oxoid Ltd, UK), and YE4 (yeast extract from Sigma Aldrich, Stockholm, Sweden).

Magnesium chloride hexahydrate (MgCl2·6H2O, 98%), aluminum chloride hexahydrate (AlCl3·6H2O, 99%), and sodium chloride (NaCl 99%) were obtained from Alfa Aesar. Sodium hydroxide (NaOH, 98%), hydrochloric acid (HCl, 36.5%), and lactic acid (C3H6O3, 88%) were purchased from Scharlau. Organic inhibitor 2-benzothiazolythio-succinic acid (BTSA 98.5%) was received from Zhengzhou HQ Material Company. All the chemicals were used as received.
The S45C carbon steel electrodes with a surface area of 1.13 cm2 were used to prepare the working electrode. For all experiments, the electrode surface was polished with SiC abrasive paper (Fujistar-Japan) from 300 to 1200 grades, rinsed with ethanol, and dried before testing. The surface compositions of electrodes after polishing were 3.14 wt% C, 0.98 wt% O, 0.08 wt% Si, 0.78 wt% Mn, 1.28 wt% S, 0.05 wt% P, 0.18 wt% Cr, 0.09 wt% Ni and the rest is Fe.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
