First step: In this step, H3PO4 donates its one acidic proton to water and form H2PO4- Second step: In this step, H2PO4− donates the second acidic proton to water to form HPO42− but H2PO4− is a weaker acid than H3PO4 (Weak acid has higher pKa value) so it is more ...
This work studies the corrosion under flowing conditions of four kinds of AISI 316L materials welded by the micro-plasma arc welding technique in different media: a basic (LiBr) and an acidic (H 3PO 4) solution by means of polarization measurements. Sensitization tests, galvanic corrosion ...
It is a weak acid with a pH of around 2.5, which means it is less acidic than vinegar. It is soluble in water and ethanol, but not in oils. Food grade phosphoric acid is used as an acidity regulator in foods like jams, cereal bars, processed me...
Is this an acid-base reaction or a precipitation reaction? AgNO3(aq) + NaCl(aq) arrow Balance the following equation in acidic solution: MnO4-(aq) + H2SO3(aq) arrow Mn2+(aq) + HSO4-(aq) Balance the following equation in acidic solution: VO43- + Fe2+ arrow VO2...
Properties of the simulated cassava wastewater are presented in Table1. The pH value of the wastewater sample is seen to be acidic and within the expected range of 3.8–5.7 from previous studies (Kaewkannetra et al.2009). A reason for the acidity could be as a result of the presence of...
Balance the following redox reaction in acidic solution: H3PO2+Cr2O72−→H3PO4+Cr3+ Redox ReactionAmong different types of chemical reactions, there is a one called redox reaction in which we can encounter both the processes of oxidation and reduction...
In the era of ecology and careful care for the environment, it becomes important to use renewable raw materials of plant origin, which are often more easil
is can be explained by a decrease of acidic functional groups and increase the basic surface groups of the carbon. e increase of activation temperature will make several functional groups is phenomenon is due decompose to form to the instability of CacOidaicndgrCouOp2s. at high temperatures [50...
Predict whether an aqueous solution of the following would be acidic, basic, or neutral. Na_3PO_4, C_5H_5NHCl, KNO_3, SO_2, CH_3CH_2CH_2COOH, Rb_2O, Fe(H_2O)_4^{3+}. Which of the following is the strongest base and why? A.\ H_2PO_4^...
