Now recall that acids are covalin compounds that have a hydrogen ion connected to a non metal and ion. So a negative ion or a poly atomic ion. Now we're gonna say generally the hydrogen ion is found at the beginning of the compound, except for citric acid. So here we have examples of some common types of acids we have hydrochloric acid, hydro sulfuric acid, hydroxy, tannic acid, phosphoric acid and acetic acid. Remember when we talked about acids, we said that acetic acid, this is one way it can be shown in this version. The hydrogen is not at the beginning, but at the end of the compound.

now as is belong to a distinct class of covalin compounds because of their characteristics in Equus solutions. Now, some characteristics of acids we have the solution taste, reactivity and how they react with litmus paper. All right, so we're gonna say dissolution acids ionized when placed in water. Here we have an example of hydrochloric acid. It would be nice in water breaking up into its H plus ion which is Aquarius plus the chloride island which is also Equus for sulfuric acid, there's two H plus in this compound so it break up into two H plus acquis plus S. +04 to minus Equus for taste. We say the presence of H plus ions gives acids a sour taste. So you can see this in natural uh citrus fruits. So we have lemons, oranges, they have a sour taste to them because of the natural assets found within them reactivity. They react with metals to form H two gas. So a good example here we have um hcl hydrochloric acid reacting with manganese, uh manganese, magnesium solid. So here, what would happen is we would have magnesium and chlorine. I'm reacting together to give me mg cl two and then the hydrogen would become each to gas. Finally, for litmus paper, this is a type of paper that changes colors in response to an acid or a base. So we're gonna say an acid will change blue litmus paper to read. So we're taking this blue litmus paper and we're dipping it into an acidic solution to show that it's acidic. The litmus paper will change red. So these are some of the common types of characteristics that you'll find with different types of acids.

Generally speaking, we're going to say that basis represent ionic compounds containing a metal cat eye on, so a positive metal ion connected to the basic and ion of hydroxide ion, which is O H minus now, basis can also be represented by nitrogen containing covalin compounds called A means. We'll talk about that later on. But these are the basic ideas when it comes to a base. So most common types of bases possess a metal connected to ohh, so if you can spot that, that is a good indication that you have a base.

now like acids bases, sharing comments certain characteristics when placing a quick solutions. So here we're gonna take a look at their dissolution their taste and feel as well as their reaction with litmus paper. So we're gonna say just like acids bases ionized when placed in water. So here we have sodium hydroxide. When I place it in water it becomes sodium ion acquis plus hydroxide ion A quiz. When I take strong to hydroxide and I place it in water it becomes strong to my on Aquarius plus two hydroxide ions. Equus. What about taste and feel? Well we're gonna say bases have a bitter taste. So bitter be basis B and they are slippery to the touch. So a great example of a base is in the manufacturing of soap. Soaps can be slippery when they're wet. Now let this paper let this paper reacts to the presence of the basic an island the hydroxide island. So if I take red litmus paper and I dip it in a basic solution it will change the red litmus paper into blue. Okay, so be base blew. Both of them have be. So that's a great way to remember the color changes associated with the base. So just remember these are the most basic characteristics of bases when you're discussing them in a quick solution.
