a认识到注水系统的腐蚀是由于CO2、 HCO3-构成了弱酸性缓冲溶液引起,从而提出了针对青海油田的提高pH值控制腐蚀理论。通过控制pH值稳定水性而不是通过通常的加入缓蚀剂的办法解决了困扰青海油田多年的注水系统的腐蚀难题。 Realized to the irrigation system corrosion is because CO2, HCO3- constituted the low-acid ...

Answer to: HClO is a weak acid (K_a = 4.0 times 10^{-8}) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.015 M in...
Which of the following is a weak acid? a) HNO3 b) HCl c) H2CO3 d) H3SO4 Which one is an acidic anhydrase? a. Na_2O \\b. MgO \\c. CO_2 What do acidic anhydrases mean? What is the pH of 0.35 M nitrous acid? The K a of acetic acid is 1.7 10 5 . What is the p ...
Bicarbonate (HCO3-) ions, more commonly known as alkalinity, can cause issues in food and beverage production and many industrial processes. Weak acid cation (WAC) ion exchange resin systems, known as dealkalisers, can be used to remove large concentrations of HCO3- in feedwater. ...
Understand the concept of pKₐ: It is a measure of the strength of an acid in solution. A high pKₐ value indicates a weak acid, while a low pKₐ value indicates a strong acid. Recognize that hydrogen gas (H₂) is not typically considered a...
(HCO3−, Cl−, SO42−, F−, and NO3−). Merck-GR grade chemicals and reagents were used to prepare the chemical solutions using double deionized water. All the glassware and apparatus were soaked with 10% hydrochloric acid (HCl) for one day and cleaned with double deionized water...
EPYC1 localizes to the pyrenoid matrix, is of similar abundance to Rubisco, and is required for Rubisco’s localization in the pyrenoid matrix, supporting a possible structural role. EPYC1 binds Rubisco, and the EPYC1 protein sequence consists of four nearly identical ∼60 amino acid repeats,...
Which of the following is a weak acid? a. HCl b. HNO_{3} c. H_{2}SO_{4} d. HBr e. H_{2}CO_{3} Identify the most acidic proton in each of the following compounds: What is the Bronsted Acid of H_2PO_4^- ...
