What are the negative effects of cloud seeding?
Risks or concerns like unwanted ecological changes, ozone depletion, continued ocean acidification, erratic changes in rainfall patterns, rapid warming if seeding were to be stopped abruptly, airplane effects, to name a few, may just not be bad enough to override the imperative to keep temperatures down.
Is AgI a solid?
The compound is a bright yellow solid, but samples almost always contain impurities of metallic silver that give a gray coloration. The silver contamination arises because AgI is highly photosensitive….Silver iodide.

What is the chemical name for AgI?
Silver Iodide
What Colour is silver bromide?
yellow
Is AgCl a precipitate?
A solution of silver nitrate is combined with a solution of sodium chloride. The resulting solution contains Na+, Ag+, Cl-, and NO3-, but AgCl is not soluble in water. Since Ag+ is now in solution with Cl- the two will combine to form AgCl, and the AgCl will precipitate from solution.
Does NH4OH form a precipitate?
With NH4OH, magnesium ion (Mg2+) give partial precipitation of Mg(OH)2. No precipitate is obtained in the presence of ammonium salts, since the latter reduces the carbonate ion concentration because of the common ion effect. NH4OH and NaOH solutions precipitate zirconium hydroxide.
What is the Colour of AgBr precipitate?
Is NaOH soluble in water?
Water
Why is NaOH soluble in water?
When sodium hydroxide (NaOH) dissolves in water, it separates into positively – charged sodium ions (cations) and negatively – charged hydroxide ions (anions). It is very soluble in water and, like all gases, it’s solubility depends on the partial pressure of the gas.
Which of the following is insoluble in NaOH?
NaOH is insoluble in ether and other non-polar solvents.
What is the chemical formula for sodium hydroxide?
NaOH
What is the scientific name of NaOH?
Sodium hydroxide
Is Sodium Hydroxide A Acid?
sodium compounds Sodium hydroxide (NaOH) is a corrosive white crystalline solid that readily absorbs moisture until it dissolves. Commonly called caustic soda, or lye, sodium hydroxide is the most widely used industrial alkali. It is highly corrosive to animal and vegetable tissue. The alkaline solutions it forms…
What is the sodium hydroxide?
Sodium hydroxide is sometimes called caustic soda or lye. Sodium hydroxide is useful for its ability to alter fats. It is used to make soap and as a main ingredient in household products such as liquid drain cleaners. Sodium hydroxide is usually sold in pure form as white pellets or as a solution in water.
Can sodium hydroxide kill you?
Sodium hydroxide is corrosive to all tissues. Concentrated vapors lead to serious damage to the eyes and respiratory system. Oral ingestion of sodium hydroxide, which occurs frequently in children, causes severe tissue necrosis, with stricture formation of the esophagus, often resulting in death.
What products have sodium hydroxide?
Sodium hydroxide is a highly versatile substance used to make a variety of everyday products, such as paper, aluminum, commercial drain and oven cleaners, and soap and detergents.
Is sodium hydroxide a solid?
Sodium hydroxide (NaOH) is a an odorless, white crystalline solid that absorbs moisture from the air. Sodium hydroxide is very corrosive.
What concentration of sodium hydroxide is dangerous?
NaOH solutions with a pH of 11.5 or greater should be considered corrosive to the skin [NIOSH 2009]. A 0.1-molar concentration (molar- ity; M) or 1% aqueous solution of NaOH has a pH of about 13 [Pierce 1993].
Is sodium hydroxide a carcinogen?
The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have not classified sodium hydroxide for carcinogenicity in humans. But this does not mean that sodium hydroxide itself is a cancer agent.
What happens if you breathe in sodium hydroxide?
Breathing in sodium hydroxide causes irritation of eyes, nose and throat, cough, chest tightness, headache, fever and confusion. In serious cases damage to the airways, a fast Page 3 Compendium of Chemical Hazards: Sodium Hydroxide Page 3 of 4 General Information heart rate and eye damage can occur.
Does sodium hydroxide absorb carbon dioxide?
Solid sodium hydroxide is hygroscopic, which means that it absorbs moisture from the atmosphere. Once it has a little moisture it also absorbs carbon dioxide which is always present in air.
Is Lye a poison?
Lyes may be harmful or even fatal if swallowed; ingestion can cause esophageal stricture. Moreover, the solvation of dry solid lyes is highly exothermic; the resulting heat may cause additional burns or ignite flammables. The reaction between sodium hydroxide and a few metals is also hazardous.
Is sodium hydroxide bleach?
Sodium hypochlorite Sodium hypochlorite is chlorine gas dissolved in sodium hydroxide. This is essentially household bleach. Sodium hypochlorite is a disinfectant that is liquid at room temperature and can be dosed with chemical feed pumps.
Is sodium hypochlorite the same as bleach?
Sodium hypochlorite, commonly known as bleach, is most frequently used as a disinfecting agent.
Where is sodium hydroxide found?
Sodium hydroxide is found in some household cleaners, such as drain cleaners, and oven cleaners. It is also used in preparation of homemade soaps, and to clean wood (such as decks) before painting. How can sodium hydroxide affect my health? Sodium hydroxide can cause serious burns.
Is sodium hypochlorite toxic?
Sodium hypochlorite itself may be toxic if ingested, or by dermal or ocular exposure. Sodium hypochlorite is corrosive and may irritate the skin or cause burning, pain, inflammation and blisters. Ocular exposure can cause irritation, pain, lacrimation and photophobia.
