Bases

how do they taste
bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule. Bases are usually soapy in nature.

List five common bases, with names AND formulas, found in homes.
Baking soda, or sodium bicarbonate (NaHCO3) has a pH of 8.3, higher than distilled water's pH of 7.0.
Borax, or sodium tetraborate (Na2B4O7*10H2O), once helped preserve mummies in ancient Egypt. Now it keeps clothes looking fresh and kills household pests. Its pH of 9.2 means it's 920 times more alkaline than pure water.
This common antacid and laxative got its milky name from its opacity. Magnesium hydroxide [Mg(OH)2] has a pH of 10.5.
The term "ammonia" refers both to an irritating gas (NH3) and to the cleaning product (NH4OH) that results from dissolving ammonia in water. Household cleaning ammonia has a pH of 11, or 50 times stronger than that of milk of magnesia.
The strongest base commercially available cleans ovens, unclogs drains, and makes a Southern breakfast better. Lye, or sodium hydroxide (NaOH), is a major component in drain cleaners

neutralization is the reaction of a hydrogen ion with a hydroxide ion to form water. ... In a Brønsted‐Lowry neutralization, an acid donates a proton to a base. In the process, the original acidic molecule becomes a conjugate base; that is, it can accept a proton.
HCl(aq) + NaOH(aq ) → NaCl (aq)+ H2O(l)- This is the balance equation of HCL and NAOH. HCL is an acid an NaOH is a base. the conjugate base is water and the conjugate acid is NaCL.
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.
The purpose of the titration is the detection of the equivalence point, the point at which chemically equivalent amounts of the reactants have been mixed.
In a titration, an analyte -- the substance whose quantity or concentration is to be determined -- is reacted with a carefully controlled volume of solution of accurately-known concentration called a standard solution.
pH indicators are weak acids that exist as natural dyes and indicate the concentration of H+ (H3O+) ions in a solution via color change. A pH value is determined from the negative logarithm of this concentration and is used to indicate the acidic, basic, or neutral character of the substance you are testing.
Difference Between Endpoint and Equivalence Point. ... An equivalence point in a titration refers to a point in which the added titrant is chemically equivalent to the analyte in the sample. Endpoint, on the other hand, is a point where the indicator changes its colour.

Acids
A Bronsted-Lowry acid like and Arrhenius acid is a compound that breaks down to give an H+ in solution. The only difference is that the solution does not have to be water.
taste
Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule. Bases are usually soapy in nature.

an acid is any proton donor, and a base is any proton acceptor. The focus of this definition is on donating and accepting protons, and is not limited to aqueous solution. The Brønsted-Lowry definition of acids and bases is one of two definitions we commonly use.
Acid - A substance that has the potential to donate a proton or accept an electron pair. ... Many chemistry texts incorrectly use this term to mean that a substance can act as either an acid or a base
