2.Like acids, aqueous basic solutions conduct and are identified as.
3.Bases react with to produce salt and.
4.Bases turn different colors.

Answer 1

Basically, a base is a molecule or ion which is able to accept a hydrogen ion from an acid. Further, they have a bitter taste and a slippery texture. A base that can be dissolved in water is known as an alkali. They also turn red litmus blue.

Complete step by step answer:
Generally, bases are bitter in taste and are slippery to touch. It is basically defined as a substance that releases hydroxide ions when dissolved in aqueous media. Moreover, alkalis are bases that are soluble in water. Some common examples of alkali are calcium hydroxide, sodium hydroxide, magnesium hydroxide etc. Now, all basic substances have similar effects on certain chemical indicators. For example, all bases have the ability to turn red litmus blue. Moreover, they are also known to impart yellow color to methyl orange and pink color to phenolphthalein.
Moreover, the pH value of basic solutions is always above 7.They react with acids to form salts and such type of chemical reaction is known as acid-base neutralization. Now, let’s fill in the blanks that are given in the question.
1.Bases tend to taste bitter and feel soapy.
2.Like acids, aqueous basic solutions conduct electricity and are identified as electrolytes.
3.Bases react with acid to produce salt and water. (neutralization)
4.Bases turn blue, indigo, violet i.e. three different colors.

Note: There are three types of bases, monoacidic, diacidic and triacidic bases. A monoacidic base is a base that produces one hydroxide ion when one of its molecules undergo complete ionization. Further in case of diacidic bases, two hydroxides ions are produced when one of its molecules undergo complete ionization whereas in triacidic bases, three hydroxide ions are produced
