-What is an Acid? How do you let out them?
An Acid is a settlement with a pH level less than seven. Acids fuck off some(prenominal) properties such as, they ar good electrolytes, corrosive, book a wreak taste, begin with oxygen, and can be used as cleaners. In order to name an mordant you must determine if they atomic number 18 binary or ternary. To name binary acids you write hydro, come about the anion, channelize the depoting to Ic and add acid. To name ternary acids, look up the anion on the polyatomic sheet, change the ending to ic (ate) or ous (ite), then add acid.

-What is a shank? How do you name them?
A base is a compound that makes hydroxide ions when dissolved in water. To take in whether a solution is a base you have to rise it on red and blue litmus papers. If both papers turn blue after dropping the solution on them, then the solution is a base. Most bases are corrosive, have a bitter taste, feel slippery, produce good electrolytes, end in OH, can be found in cleaners, and have a pH greater than seven. You name bases the same direction you name ionic compounds by writing the cation and anion, then balancing the ionic charges.

-Strong and Weak Acids and their uses.
Acids are classified as toilsome and debilitated, depending on the degree they iodize in water. Strong acids are completely iodized in aqueous solutions.

Unlike weak acids they only iodize slightly in an aqueous solution. To reclaim whether the acid is hard is by using the equilibrium expression. From that you would gravel the dissociation constant (ka), which says the higher the (ka) value the wholesomeer the acid and the set about the value the weaker the acid. Also on the pH scale the disappoint the value the stronger the acid.

-Strong and Weak Bases and their uses.
Bases are classified as strong and weak, by checking how they answer in aqueous solutions like, weak bases react with water to form the hydroxide ion and the conjugate acid of the base. Unlike, strong bases which dissociate completely into metal ions and hydroxide ions in...If you want to add a full essay, order it on our website: Orderessay
