Answer: This is because the salts of strong acid versus strong base reaction upon hydrolysis again forms a strong acid and a weak base. Hence, these hydrolysis products would convert into ions as soon as they were formed. For example, NaCl is a salt of strong acid HCL and strong base NaOH. On hydrolysis: NaCl + H 2 O → NaOH + HCl
Moles of acid = 1.638 x 10-3 moles since the stoichiometric ratio is 1HX : 1NaOH Step 3: Calculate the molar mass of the unknown monoprotic acid. 81.20 g mol-1 Part ii) Step 1: Calculate the mass of the halogen. 81.20 – 1.0 = 80.2 Step 2: Use the periodic table to identify the halogen. 80.2 ≈ Bromine (79.9)
acid-base reaction, a type of chemical process typified by the exchange of one or more hydrogen ions, H+, between species that may be neutral (molecules, such as water, H2O; or acetic acid, CH3CO2H) or electrically charged (ions, such as ammonium, NH4+; hydroxide, OH−; or carbonate, CO32−). It also includes analogous behaviour of molecules and ions that are acidic but do not donate
The equivalent weight of an acid can be defined as the mass of an acid that contains one equivalent of hydrogen ions. The pH of an acid can be computed using the Henderson-Hasselbalch equation, which is written as pH = pK a + log ( [A – ]/ [HA]) 1. In this equation, pK a is the logarithm of the acid’s K a value, [A -] is the concentration An acid-base titration is the determination of the concentration of an acid or base by Common indicators, their colours, and the pH range in which they change colour are given in the table above. [14] When more precise results are required, or when the Give one example of a weak acid and explain why it called
Acids, bases and salts. For example, if the reading at the start is 1.00 cm 3 and the final reading is 26.50 cm 3, You can ignore the first (rough) titration result.
As a student, when I was taught titration, it was accompanied by a long laundry list of scenarios: titration of a strong acid with a strong base, titration of a strong base with a strong acid, titration of a weak acid with a strong base, and titration of a weak base with a strong acid. Each of these scenarios were followed by a graph that corresponded to changes in pH, like the following

We start with the reaction equation: HCl + NaOH → NaCl + H 2 O. One mole of hydrochloric acid reacts with one mole of NaOH. For titration 0.04356 L×0.1023 M=4.456×10 -3 mole of base was used, so there was 4.456 mmole of hydrochloric acid in every 25.00 mL of solution taken from the volumetric flask. Volumetric flask is 10 times larger than
Its acid-base titration using NaOH as a titrant results in the appearance of a small pO drop at the equivalence point ( 1 pO unit), which corresponds to the ligand number value —0.5. This allows us to conclude that the acid-base titration runs in one step, and the final product is di-germanate ion, Gc202
Procedure of Acid-Base Titration. Steps involved in the acid-base titration involve: First, you need to clean and dry the conical flask, burette and funnel required to perform the experiment.; Then, fill the burette with a standard solution or titrant of known concentration using a funnel. After that, accurately measure the volume of the analyte solution or titrand and add it to the conical flask.

In an acid-base reaction, the molecule of acid would react with the base to generate an anion of the acid and water molecule: HA (acid) + OH – (base) A – + H 2 O (Salem)
