Amazingly bad. You won't make a bomb or anything. What you'll get is an exothermic reaction which at best will make a nasty mess and at worst will injure you, depending on the pH of the acid and base. By the way, exotherms are chemical reactions that dump heat, so you might get burned too.
Chlorine bleach is a base so a base and an acid will give you a salt (or ionic compound) and water. In order to come up with the equation for the reaction, you would need the formula of chlorine bleach and of the acid you are reacting it with.
When hypochlorite (such as bleach) is mixed with acid, a reaction occurs that releases chlorine gas. This gas can be harmful if inhaled, irritating to the eyes and respiratory system. It is important to never mix bleach with acids, as it can create a hazardous environment.
Mixing sulfuric acid and bleach can create toxic chlorine gas, which can be hazardous if inhaled. The reaction can also produce heat and cause splattering, so it is not recommended to mix sulfuric acid and bleach.
A deadly gas will form from the mixing of ammonia and bleach. Pouring water into strong acid will cause an explosion; pour the acid slowly into water if you must mix them.
Bleach is acid
Bleach typically contains sodium hypochlorite, which is a strong oxidizing agent rather than an acid. However, when mixed with certain acids, bleach can release toxic chlorine gas. It is important to never mix bleach with acids or any other cleaning products.
Mixing sodium hypochlorite (bleach) and citric acid can produce chlorine gas, which is toxic and can be harmful if inhaled. It is not recommended to mix these two chemicals together as it can create a hazardous situation.
When acid is mixed with bleach, it can produce chlorine gas, which is toxic if inhaled. It is important to avoid mixing acid with bleach, as it can lead to serious health risks and should only be done in a controlled environment by trained professionals.
Bleach contains OCl- ion. So it is a acid.
Mixing boric acid with bleach can produce toxic chlorine gas, which can cause respiratory irritation, coughing, chest tightness, and in severe cases, can lead to difficulty breathing, lung damage, and even death. It is important to never mix these two chemicals together.
It says right on the bottle "do not mix with chlorine bleach to avoid irritating fumes"
Never mix bleach and ammonia, the gas from mixing the two is very toxic. Always dilute when using as a stain remover, or you will have holes in your clothing. Be careful when mopping floors with bleach in a home where animals reside. If you are cleaning with undiluted bleach, ventilate!
