What is the rule for mixing acids and water?
Always add acid to water, not water to acid. This helps to prevent the acid from splashing back and causing potential harm, as adding water to acid can lead to an exothermic reaction and potentially dangerous spattering.
Chemical formula for oxalic acid dihydrate?
The chemical formula of the oxalic acid is C2O4H2.
How physical properties different from chemical properties?
they are different because a chemical change is a change in which you apply heat to a object to change it in form physical change is when you change a form it size or shape but do not apply heat.So you will know the differnce because when you add heat to any object its a chemical change but expccpt boiling water
What is the procedure to neutralizing an acid?
Add an alkali. Remember the general chemical reaction Acid + Alkali = Salt + Water. However, if the acid has been ingested by a human, then give a carbonate, because the 'raw' alkali can also do damage to a human. The chemical reaction of a carbonate is Acid + Carbonate = Salt + Water + Carbon Dioxide(burp!!!). Common carbonates are sodium bi-carbonate(baking powder). or proprietary medicnes such as 'Milk of Magnesia' Milk of magnesia is a suspension of magnesium carbonate and magnesium hydroxide. .
Is dissolving carbon dioxide in water a physical or chemical change?
It's a physical change because carbon dioxide still has it's same properties. It is not changed.Added:Even if you dissolve it in water it is still there thus making it a physical change and not a chemical change. If it were a chemical change then it would be changed for example, fire or burning things like logs and so forth. Dissolving something in water is not changing it completely it only has a minor change in how you see it, thus it is a physical change.The only 'chemical' change might be considered to be the protolysis of water being slightly enhanced by the hydrogen bonding to carbon dioxide molecules. But that is more a (very weak) 'chemical' change of water molecules rather than of CO2 molecules:(CO2)aq + 2 (H2O)l > (Cl-)aq + (H3O+)aq
What is the chemical formula for when you add a base to an acid?
When you add a base to an acid, they undergo a neutralization reaction to form water and a salt. The general chemical formula for this reaction is: acid + base → salt + water
Is neutralizing a chemical or physical change?
Neutralizing is a chemical change, as it involves a chemical reaction between an acid and a base to produce a salt and water. This reaction results in the formation of new substances with different chemical properties than the original acid and base.
How can you change water chemically?
add a chemical.
Do you add water to acid or add acid to water?
you add acid to water
How do you change the pH of a water solution?
Add an acid or a base to it.
How can you change the concentration of acid?
By diluting it with water or neutralising it with a base or alkaline
If you add water to an acid will it weaken the acid?
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.
What do you add to sulpuric acid to get iron sulphate?
You would add iron oxide (rust) to sulfuric acid to produce iron sulfate and water in a chemical reaction.
If one wants to top up a tank of muriatic acid should one first add the water or concentrated acid?
When mixing acid and water, always add the acid to the water, and add it slowly. Never add the water to the acid.
Can Neutralize a base physical or chemical?
Add a strong base to strong acid and you will neutralize it. Similarly, add a strong acid to a strong base and it will be neutralized. For example:- HCl + NaOH ----> NaCl + H2O You add a strong base to a strong acid and get a neutral salt and water.
Is adding alkali to acid a chemical or physical change?
This is a chemical change, because the carbon dioxide is created from the ingredients when placed in solution. The effervescence is caused when citric acid and sodium bicarbonate combine to form sodium citrate, releasing carbon dioxide gas.
When you add zinc metal to hyrochloric acid does a chemical physical change occur?
Yes, hydrogen gas and zinc chloride are produced
