What else can I help you with?
How do you stop bacteria from multiplying?
Common bleach will kill bacteria. Not only does it whiten things, but it is also a 'Bacteriocide'. It is the chlorine in bleach that does the job. That clean sharp smell you have with bleach are a few molecules of chlorine gas being liberated. Chlorine gas is poisonous, so to contain it, it is sold as bleach.
What is the oxidation number of HClO?
For HClO oxidation No. is '0' . It is a neutrally charged molecule. However, The chlorine atom is in oxidation state (+1). How so???? you may ask . Using oxygen as that standard at '-2' , and hydrogen at '+1' We create a little sum +1 + Cl -2 = 0 ( overall charge on the molecule). Collecting terms Cl - 1 = 0 Cl = + 1 as required. NB When dissolved in water chlorine disproportionates. That is it simultaneously oxidises and reduces., Cl2(aq) = Cl^(+)(aq) + Cl^(-)(aq) It reacts with water molecules to form ;- Cl2 + H2O = HClO + HCl The supply of drinking water from public sources has chlorine bubbled through to act as a bacteriocide (kill the bugs). So tap/faucet water is a very weak solution of hydrochloric acid(HCl) and Hydrogen chlorate(bleach)(HClO). It won't harm you, because the solution is so weak, but just enough to kill the bugs.
What type of chemical agent retards bacterial growth?
Antibiotics are chemical agents that retard bacterial growth by targeting specific components of bacterial cells, which can inhibit their growth or kill them. Examples include penicillin, tetracycline, and ciprofloxacin.
Is bleach fungicidal?
Yes, bleach is fungicidal, meaning it can kill fungi and mold. It is often used as a disinfectant to eliminate mold and mildew on surfaces. However, it is important to use bleach carefully and follow proper safety precautions.

Where Chlorine used For Killing Bacteria?
In the Water supply to houses factories etc., Chlorine is dissolved in the water as a bacteriocide. Chlorine has the ability to disproportionate in water. H2O + Cl2 = HCl + HClO HCl is hydrochloric acid and HClO is Bleach. Such is the amount put in the water supply you don't smell or feel it. However, if has the effect of killing bacteria.
What is the technical process of purifying water?
The technical process of purifying water typically involves several steps, such as filtration, sedimentation, coagulation, disinfection, and sometimes reverse osmosis. These methods help remove impurities, bacteria, and contaminants from water to make it safe for consumption. The purified water is then often tested to ensure it meets safety standards before being distributed for use.
Can you get sick if the pool has no chlorine in it?
Yes, and sadly enough, there are a slim couple of particular strains of bacteria that can grow even in a properly chlorinated pool, crypto-sporidium just to name one. But yes you can get sick from swimming in a pool that has no sanitizer. Still probably cleaner than any lake or pond you've ever swam in ;-)
What is pH of ordinary water?
pH of puredistilled de-ionised water at 25oC is pH = 7. However, tap water, because of additives put inot it by the water-companies, decreases the pH to about pH = 6.7 NB One of the additives is Chlorine gas. In water, chlorine simultaneously form HCl & HClO, both of which are acids. Chlorine is added as a bacteriocide to water.
An element in household bleach that also may be present in drinking water?
Chlorine. A molecule of chlorine has the ability to disproportionate in water. That is it simultaneously oxidises and reduces. Cl2 = Cl-Cl = Cl^(-) + Cl^(+) Disproportionation). Cl2 + H2O = HCl(reduced) + HClO(oxidised). At a water treatment plant, chlorine gas is bubbled through water, in order to act as a bacteriocide, so the water is drinkable/potable. Household water contains minute traces of hydrochloric acid(HCl) and hypochlorous acid(HClO). It is the hypochlorous radical 'ClO^(-)' that is found in bleach. (NaClO or Ca(ClO)2
Does pH of 2 - 3.8 help to kill bacteria?
pH is a measure of acidity or basicity of a solution, and is not an actor capable of verbing things. A bacterial cell living in an environment with too much acid or too much base (relative to what it is set up for) will tend not to do well and perhaps die, depending on how its membranes are set up. Acidophiles like and do well in low pH environments, and v.v.
A chemical that kills bacteria or slows their growth is called?
Antibiotics, is a generalized answer, however there are different types of antibiotics. There are Bacteriostatic Agents which answer your question in that they inhibit the growth of bacteria which is a microorganism Then there are bactericidal agents (bacteriocide) and they kill bacteria which is a microorganism Agents having the suffix -cidal kill organisms, agents having the suffix -static merely inhibit their growth and reproduction.
What is the different between bactericidal and bacteriostatic?
BACTERIOCIDE: The agent which kill bacteria is called bacteriocidal it can be done by heat of any chemical. BACTERIOSTATIC: The agent which inhibit the growth and reproduction of bacteria but do not necessasarily kill the bacteria.
Why do you add chlorine into tap water?
Chlorine is added to water in order to act as a bacteriocide(kill the bugs). In water , chlorine disproportionates. That is it form a minus ion and a positive ion. Cl2 = Cl^- + Cl^+ These two ions combine with water in different ways. They form hydrochloric acid (HCl) and hypochlorous acid (HClO)(bleach). Here is the balanced chemical reaction. H2O + Cl2 = HCl + HClO. The quantity of chlorine added is so small that these two chlorine containing compounds have no effect on humans, but they do kill the bugs.
