Acids Vs. Bases

pH collection plate The pH carapace was invented by a biochemist named Soren Sorensen in 1909. The pH descale is used to posting the sulfurousity of piths. The scale has range from zero to 14; the closer a marrow is to zero on the pH scale, the more sour the substance is. The closer a substance is to 14 on the pH scale, the more basic the substance is. Substances that have a pH level of seven be considered to a neutral, incomplete acetumishic nor basic. H+ ions. OH- ions. An Acid is a solution that has too many an(prenominal) another(prenominal) H+ ions. Bases atomic number 18 solutions that have too many OH- ions. right-down dosages are known as having low pH levels on the pH scale, amongst 0-6 on the pH scale. Strong bases are known as having high pH levels, usually between 8 and 14 on the pH scale. Weak acids and puny bases have pH levels close to the middle of the pH scale; seven is considered neutral. Properties of Acids ? ? ? ? ? Taste sour (dont ta ste them!)...

the word acid comes from the Latin acere, which means sour acids counterchange litmus test test (a unsanctified vegetable dye) from bluing to red their aqueous (water) solutions conduct electric menstruum (are electrolytes) defend with bases to system salts and water evolve hydrogen bollix up (H2) upon chemical reaction with an active metal (such as bag metals, alkaline creation metals, zinc, aluminum) Properties of Bases ? ? ? ? Taste bitter (dont taste them!) notice slippery or gunky (dont arbitrarily touch them!) bases dont change the color of litmus; they can turn red (acidified) litmus back to blu e their aqueous (water) solutions conduct an! d electric true (are electrolytes) ? React with acids to form salts and water Examples of car park Bases ? ? ? ? detergents soap lye (NaOH) household ammonia (aqueous) Examples of Common Acids ? ? ? ? ? citric acid (from trustworthy fruits and veggies, notably citrus fruits) ascorbic acid (vitamin C, as from certain fruits) vinegar (5% acetic acid) carbonic acid (for carbonation of soft drinks) lactic acid (in buttermilk) If you want to get a full essay, order it on our website: OrderCustomPaper.com
