Can substances be acidic and alkaline at the same time?
No, a substance cannot be both acidic and alkaline at the same time. Acidity and alkalinity are opposite characteristics on the pH scale, ranging from 0 to 14. A substance that is acidic will have a pH below 7, while a substance that is alkaline will have a pH above 7.
Is it necessary for every compound to be acidic or basic or neutral?
To measure the pH of a substance it has to be in solution so if the substance is insoluble you cannot measure its pH. A basic substance is not the same as an alkaline substances. A basic substance is one which can neutralise an acid. An alkaline substance is a solution of a base. For example, chalk (calcium carbonate) is basic as it neutralises acids but as it is insoluble, it is not an alkali. However solid sodium hydroxide can be described as a base as it can neutralise an acid and as it is soluble in water, a solution of sodium hydroxide is both a base and an alkali.
When the acidic solution is added to the basic solution what happens to the pH does it increase decrease or stays the same?
When an acidic solution is added to a basic solution, the pH will decrease. This is because the addition of the acidic solution will neutralize some of the hydroxide ions in the basic solution, resulting in a decrease in pH.
Is amphiprotic the same as neutral?
Amphiprotic is not the same as nuetral. An amphiprotic substance is one which has the characteristics of both an acid and a base, and can act as either depending on which other substance it is placed with. A neutral substance is unreactive.
What is an example of neutral substance?
A neutral substance is any substance that has the same number of protons and electrons. One common neutral substance is carbon dioxide. Another common neutral substance is nitrogen gas, N2.

Is amino acid is acid?
Amino acids are, as the name suggests, both amines (basic) and acids (acidic, of course). They fall into the category of compounds known as zwitterions: chemicals that have an acidic part and a basic part in the same molecule.
When the acidic solution is added to the basic solution what happens to the pH does it increase decrease or stays the same?
When an acidic solution is added to a basic solution, the pH will decrease. This is because the addition of the acidic solution will neutralize some of the hydroxide ions in the basic solution, resulting in a decrease in pH.
Can a base like hydroxide make an acidic solution if its pH is lower than 7?
In short, it is impossible for a base to be acidic: it follows from definition that if something were basic, it cannot be acidic at the same (this is different from amphoteric substances, which react with both but are not both themselves). As well as this, a solution with pH < 7 is acidic; again by definition, if it causes a pH lower than 7 it cannot be basic.
Is silicon acidic or basic?
Silicon is not acidic or basic in the same way that common acids and bases like hydrochloric acid or sodium hydroxide are. It is a metalloid element that does not exhibit typical acidic or basic properties.

Is nitric and neutral the same thing?
No, nitric and neutral are not the same thing. Nitric refers to the compound nitric acid (HNO3), which is an acid, while neutral refers to a solution or substance that has a pH of 7, neither acidic nor basic.
Is adenine polar or non polar?
Alanine is an amphoteric substance: both acidic and basic at the same time. However, it is neutral in a pH = 6.1 solution: CH3CH(NH3+)COO- It is positvely charged ( by excess of H+) at lower pH sol'n CH3CH(NH3+)COOH and negatively in pure water or more basic solution CH3CH(NH2)COO-.
How much acid in neutral acid?
If a substance is said to be neutral, the same compound cannot be acidic.
The specific heat of substance A is greater than that for substance B If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these s?
The specific heat of substance A is greater than that for substance B. If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these samples, substance A will have a lower temperature than substance B.
