There's a lot of it on the first floor.,It's a lot of pressure on me hehe, but it seems to be copied on which network.,It's a little wrong.,Most of the writing is chemical.
Let me tell you about it
Physical properties of common salts: potassium, sodium, ammonium, nitrate are easily soluble in water; Most of the positive salts have good thermal stability and high melting and boiling points (except nitrates), such as NaCl, KCl, CuCl2, Na2SO4 ......; Most salts are denser than water, and almost all salts are solid at room temperature.
Physical properties of common acids: the density of inorganic acids is generally greater than that of water; There are many gaseous and liquid states, such as HCl, HSO4, acetic acid, etc.; Mostly corrosive; The more hydroxyl groups contained in organic acids, the less dense they are, such as density: CH3COOH>CH3CH2COOH>CH3(CH2)2COOH.
Most inorganic acids can turn litmus red.
Ok, that's all

Salts are generally crystals, some soluble in water, some insoluble in water, insoluble in mailing solvents (except for reactions) are usually ionic crystals, high melting point, ionization of anions and cations in water, salt solutions can conduct electricity, and they are not conductive, especially for example, AlCl3 is a molecular crystal, and some salts can make proteins salted out.
Acid is easily soluble in liquids in water, only silicic acid solids are insoluble in water, and the solution ionizes hydrogen ions and conducts electricity.

Salt: has the effect of reducing the freezing point of liquid;
Soluble in liquids; Not easy to sublimate.
Acid: Acid solutions are denser, like vinegar, with a higher density than water and a lower boiling point than water.
-
Salt is described in terms of color, state, melting point, boiling point, solubility, density, pressure, etc., and acid is described in terms of color, state, melting point, boiling point, solubility, concentration, volatility, water absorption, corrosiveness, etc.
Different substances have different properties, you don't want the physical properties of all salts and acids!!

Dude, do you want to make a barbecue restaurant or do you want to eat it at home Barbecue sauce is not a single kind There are grilled vegetables Grilled fish Grilled seafood How do you say I tell you Everyone is good at different I have made grilled fish Grilled ribs and skewers of various flavors There are more than a dozen I think if you want to open a store and you don't want to spend money Then go to Oriental cuisine to find a recipe or go to the food network to find it If you ask on this Most of them are still the kind that charges on the ** and are not certain I am from Shenyang If you have ideas, you can contact me I will teach you If you don't need money, just make a friend.
There are roughly six levels of learning physics, that is, first to understand, then to remember, to practice, to become proficient, to practice to make perfect, to innovate, from the initial goal of basic knowledge, and finally to the highest level of learning physics. >>>More
