What is the definition of an acidic solution?

An acidic solution is any aqueous solution which has a pH < 7.0 ([H+] > 1.0 x 10-7 M). While it’s never a good idea to taste an unknown solution, acidic solutions are sour, in contrast to alkaline solutions, which are soapy.

What is basic solution?

A basic solution is an aqueous solution containing more OH-ions than H+ions. In other words, it is an aqueous solution with a pH greater than 7. Basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

What is acidic and basic mean?

pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic.

What is a base defined as?

A base is a substance that can neutralize the acid by reacting with hydrogen ions. Most bases are minerals that react with acids to form water and salts. Bases include the oxides, hydroxides and carbonates of metals. The soluble bases are called alkalis. Sodium hydroxide is an alkali.

What is the definition of basic in chemistry?

base, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis).

What’s the most basic solution?

Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic.

What is the difference between acidic basic and neutral solutions?

A solution with a pH of 7 is classified as neutral. If the pH is lower than 7, the solution is acidic. When pH is higher than 7, the solution is basic. These numbers describe the concentration of hydrogen ions in the solution and increase on a negative logarithmic scale.

What is a acid in chemistry?

(A-sid) A chemical that gives off hydrogen ions in water and forms salts by combining with certain metals. Acids have a sour taste and turn certain dyes red. Some acids made by the body, such as gastric acid, can help organs work the way they should. An example of an acid is hydrochloric acid.

What is an acid in chemistry?

What do you mean by base?

1 : a thing or a part on which something rests : bottom, foundation the base of a statue the base of the mountain. 2 : a starting place or goal in various games. 3 : any of the four stations a runner in baseball must touch in order to score.

What is a basic pH?

pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic).

What is a base in chemistry?

Table of Contents. base, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis).

What is base explain?

Which solution is most acidic?

The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7.
