Indicators are substances that change color depending on the pH of the solution. For example, litmus paper turns red in acidic solutions and blue in basic solutions. When an acid is neutralized by a base, the litmus paper will change from red to blue or vice versa, depending on the ...
A neutralization reaction is a reaction when a strong acid reacts with an equally strong base or when a weak acid reacts with an equally weak base. The product of neutralization reactions is a neutral salt and water solution. The products of acid-base reactions vary in acidity and basicity....

Many of these occur naturally in plants and were recognized historically as substances capable of differentiating between acidic and alkaline solutions. Typical acid–base indicators are organic molecules, usually of high molecular weights, that possess weakly acidic or basic properties. Thus, they act ...
In chemistry and cooking, many substances dissolve in water to make it either acidic or basic/alkaline. An acidic solution has a pH less than 7 while a basic solution has a pH greater than 7. Aqueous solutions with a pH of 7 are considered neutral.1Acid-baseindicatorsare substances used ...
As an example of how specific acid–base catalysis works, consider the hydrolysis of ethyl acetate (Scheme 4.6). This is an exceedingly slow reaction at neutral pH because both the nucleophile (H2O) and the electrophile (the carbonyl of ethyl acetate) are unreactive. The reaction rate could ...
is measured on the pH scale, which ranges from 0 to 14. The lower the pH number is, the more hydrogen ions that are being released. Water has a pH of 7, which is neutral on the pH scale. Allacidshave a pH lower than 7. A pH greater than 7 indicates analkali, or base. ...
