Acids can dissolve substances through a chemical reaction. Increasing the concentration of an acid increases the rate at which it can dissolve other substances, making it more dangerous if touched. Acids can be weakened by diluting them with water, decreasing the potency of the acid and making it safer.
It's media made from scratch, with every single ingredient defined and listed separately. This media is used only when you want to determine which nutrients a microbe absolutely must have and which ones it can make. -The medium is chemically defined. This means that it only contains pure organic and pure inorganic compounds that are specified by an exact formula.The content varies little between sources. -Minimal media, for fungi, contain only a few essential compounds like salt and amino acids, other types of synthetic media are useful in research and cell culture when the exact nutritional needs of the test organisms are known.
Generally not much. The glass fiber is inert to most normal things - water, salt, UV radiation, oils, fuels, moderate acids and alkalies. Different resins are used to bond the glass fibers together, but they usually have good resistance to all of the above except UV radiation. This is why fiberglass structures usually have a gellcoat or painted surface to protect it from the sunshine. With long-term sun exposure, gellcoats and paints will fade or chalk. This is an appearance issue and doesn't harm or change the fiberglass underneath. The two most common resins used with fiberglass are polyester resins and true epoxies. Fiberglass made with polyester resins can form blisters when it is in continuous contact with water for long periods of time (years). Osmosis causes the water to soak in between the layers of fiberglass. Since polyester resin is cheaper than epoxy, it is commonly used in consumer products like boats. It is common for older boats that have been kept in the water for years to develop blisters below the waterline. The blisters don't really seem to cause any problems, but boat owners hate them and will sometimes pay thousands of dollars to have the outer layer of the hull striped off and replaced. Epoxy resins don't generally have this problem.
Concentrated acids are generally more hazardous than dilute acids. This is because concentrated acids have a higher concentration of the corrosive substance, making them more reactive and likely to cause severe burns or damage upon contact with skin or other materials. Dilute acids are typically less reactive and pose a lower risk of causing harm.
Concentrated and dilute acids will give different pH values
when same volumes taken,In concentrated there are many more moles of H+ than dilute one.
Yes, concentrated acids and bases are more corrosive than dilute acids and bases
react with some metals to produce salt and hydrogen gas.
You can determine if an acid is concentrated or dilute by looking at its molarity. A high molarity indicates a concentrated acid, while a low molarity indicates a dilute acid. Additionally, concentrated acids are usually labeled as such on their packaging.
This is necessary only for very concentrated acids or bases.
Yes, acids can be dangerous in concentrated forms because they can cause burns on skin, damage to tissues, and corrosion of materials upon contact. Proper safety precautions, such as wearing protective gear and working in well-ventilated areas, should be followed when handling concentrated acids.
strong acids and bases dissociate completely; weak acids and bases dissociate only partially. In contrast, the term dilute and concentrated are used to indicate the consentration of a solution, which is the amount of acid or base dissolved in the solution. It is possible to have dilute solutions of strong acids and bases and concentrated solutions of weak acids and bases.
because if you get the acid on you ,your skin will burn so you have to dilute it so its safer
Not necessarily. The rate of reaction depends on various factors such as concentration, temperature, and nature of the acid. In some cases, a dilute acid may react more quickly due to better access to the reacting surfaces.
Adding water to an acid will dilute the acid, making it less concentrated and less acidic. However, it does not change the chemical properties of the acid itself. This can be a safer way to handle acids, as highly concentrated acids can be very corrosive.
