Answer:
No
Explanation:
The pH scale is a scale graduated from 0-14 which shows the degree of acidity of alkalinity of a substance. The pH scale is graduated in such a way that 0-6.9 indicates acidity, 7.0 indicate a neutral substance, while a pH of 8-14 indicates alkalinity respectively.
There are three main definitions of acids/bases
- Arrhenius definition
-Brownstead-Lowry definition
-Lewis definition
Arrhenius explains acids as any substance that produces hydrogen ions as its only positive ion in solution while a base produces hydroxide ions as its only negative ion in solution. The pH scale is based on corresponding values of pH derived from aqueous solutions of these substances.
However, not all acids/bases produces hydrogen or hydroxide ions in solution. Brownstead-Lowry definition of acids and Lewis definition of acids could be extended to nonaqueous media where the pH can not be measured as there are no hydrogen or hydroxide ions present in the solution.
This implies that pH measurement may not apply to acids/bases in the all the categories of acids/bases hence it can not be utilized for all acids and bases.
Arrhenius - sodium carbonate
Brownstead-Lowry - concentrated HF
Lewis acid - AlCl3

The energy source of tsunami waves is much greater
Explanation:
The major difference between a tsunami waves and ripple waves is that the energy source of tsunami waves is much greater compared to ripple waves.
Tsunami waves carry more energy compared to just a disturbance resulting from a ripple caused by dropping of a stone.
- A tsunami is a large water wave caused by the displacement of water usually by an earthquake.
- An earthquake is a releases elastic waves suddenly within the earth crust.
- Water bodies at the epicenter are disturbed sending huge volume of energetic water loads to the land.
- A ripple is just a product of a stone dropped inside the water.
Tsunamis are more energetic compared to ripples in water.

NaCl at 100°C= 40 gram
NH₂Cl at 90°C= 70 gram
<h3>What is solubility?</h3>
Solubility is defined as the maximum amount of a substance that will dissolve in a given amount of solvent at a specified temperature.
Amount of a substance (called the solute) that dissolves in a unit volume of a liquid substance (called the solvent) to form a saturated solution under specified conditions of temperature and pressure. Solubility is expressed usually as moles of solute per 100 grams of solvent.
Hence,
at 70°C = 130 gram
NaCl at 100°C= 40 gram
NH₂Cl at 90°C= 70 gram
