Question
Which of the following statements is incorrect?
- Bases are corrosive.
- Acids are substances that taste bitter.
- Acids are substances that taste sour.
- Acids are corrosive.
Hint:
Acids are substances that taste bitter is the incorrect statement as acid tastes sour.
The correct answer is: Acids are substances that taste bitter.
- While many bases are bitter chemicals and are in fact alkaline, this is due to the fact that naturally occurring bitter compounds frequently include amine groups, whereas acidic compounds are thought to taste sour due to their hydrogen ion concentration. Amine bases are fragile.
- Acids have a sour flavor.
- Bases (or alkalis) like potassium hydroxide and sodium hydroxide are corrosive because they penetrate deeply and break down fatty acids in skin tissue.
- Any chemical that will destroy an object's structure is referred to as corrosive. They could be oxidizers, bases, or acids. Surfaces decay when they come into contact with them.
