Is NaClO4 an acid or base?

Is NaClO4 an acid or base?

NaClO4 is not an acid at all. Cations and Chloride anions to form perchloric acid also, NaCl is not a base, salt, none. Other hand is a strong mineral acid, such as hydrochloric acid, with a =. Cations and Chloride anions you use ClO4 rather than just Cl a =.

Is Na2SO4 an acid or base or salt?

Sodium sulphate (Na2SO4) is formed by a reaction between sodium hydroxide and sulphuric acid which are strong base and acid, respectively. Thus, it a neutral salt with a pH of 7.

What is the purpose of reference electrode?

The role of the reference electrode is to provide a stable potential for controlled regulation of the working electrode potential and in doing so allow the measurement of the potential at the working electrode without passing current through it. An ideal reference electrode should also have zero impedance.

What are the two main chemicals used in calomel electrode?

A saturated water solution of KCl (potassium chloride) is in contact with the mercury and the mercury(I) chloride (also known as “calomel”). Linking the electrode to the solution in which the other electrode is immersed is a porous frit, which is a salt bridge.

What is normal calomel electrode?

The number of electrons n is 2. The standard reduction potential of normal calomel electrode (E0el) and reduction potential of saturated calomel electrodes (Eel) are 0.27 and 0.33 volt respectively. Hence, option A ) 0.1 M is the correct answer.

What is meant by calomel electrode?

Calomel electrode is a type of half cell in which the electrode is mercury coated with calomel (Hg2Cl2) and the electrolyte is a solution of potassium chloride and saturated calomel.

What is the indicator electrode?

In redox methods an indicator electrode is used to sense the presence or change in concentration of the oxidized and reduced forms of a redox couple. Usually, the indicator electrode is an inert noble metal, such as Pt, and the potential of the cell is measured vs a reference electrode.

What is secondary electrode?

In general, secondary reference electrodes are electrodes of the second kind, i.e. metal electrodes coupled to a solubility equilibrium of a salt of this metal and an electrolyte solution containing a fixed concentration of the anion of the sparingly soluble metal salt.

What is primary and secondary standard electrode?

Explanation: Standard hydrogen electrode is considered as the primary reference electrode. Calomel electrode whose potential is obtained by connecting it to the standard hydrogen electrode acts as a secondary reference electrode.

Which of the following is a secondary reference electrode?

Explanation: Mercury chloride is known as calomel. The most important general purpose secondary electrode is calomel electrode.

Which one is the primary reference electrode?

The Standard Hydrogen Electrode (SHE) is considered the primary reference electrode as it defines the zero point in the electrochemical scale.
