Basic.
pH<7 -----> Acidic pH=7------> Neutral pH>7------>Basic or Alkaline
Alkaline substances are basic, having a pH greater than 7. They are the opposite of acidic substances, which have a pH less than 7.
Probably acidic, neutral, and basic. A neutral pH is 7, and anything below that to zero is acidic. Anything above that to 14 is basic. I thought that 14 was alkaline...??
Pure water is not neutral it is amphoteric which means with bases(alkaline) it acts as acidic and with acids it acts as basic(alkaline)
c.) basic because it is above 7, which is neutral.
No, not all soaps are alkaline in nature. Soaps are the salts of fatty acids and can be either alkaline or neutral depending on the type of fatty acid used in their production. Traditional soaps made from fats with high alkaline content are alkaline, while syndet bars (synthetic detergents) are neutral or slightly acidic.
Calcium carbonate (CaCO3) is a basic substance because it is an alkaline compound. When dissolved in water, it will produce a slightly basic solution.
Potassium nitrate is a neutral salt, t is neither acidic nor alkaline.
No, pH 5.5 is considered acidic on the pH scale, which ranges from 0 (most acidic) to 14 (most alkaline or basic). A neutral pH is 7.
Limestone is a basic (alkaline) substance. It has a pH greater than 7, meaning it helps to neutralize and balance acidic conditions in soil or water.
Tap water is typically slightly basic, with a pH level around 7 to 8. This means it is not acidic but rather neutral to slightly alkaline.
