What else can I help you with?
Is Hydrogen sulfide gas acidic?
Yes, hydrogen sulfide gas is considered slightly acidic when dissolved in water, as it forms weakly acidic hydrosulfuric acid.
Why can the pH of freshly boiled deionized water slowly become more acidic when left exposed to the atmosphere?
Because the air contains CO2,which is dissolved in the water and produces carbonic acid. Same effect asacid rain.
Is PH2 acidic?
PH2, known as phosphine, is a weakly acidic compound. In water, phosphine can react to form PH4+ and OH- ions, indicating its weak acidic nature.
Deionized water acid or base?
Deionized water is neutral, but it can act as an acid in the presence of strong base or as a base in the presence of strong acid.Dissociation constant for water:Kw = 1.0 x 10-14
Is thiourea acidic or basic?
Thiourea is a weakly acidic compound with a pKa value of around 10.5.
Is mgc03 weakly acidic or basic?
MgCO3 (Magnesium Carbonate) is a metal carbonate and reacts with an acid to produce salt + water + CO2. Thus, it is weakly basic.

Is 5 on the pH scale acidic or alkaline?
If a substance has a pH of 5, it is said to be weakly acidic.
Is thiourea acidic or basic?
Thiourea is a weakly acidic compound with a pKa value of around 10.5.
Is deionized water an element?
The deionized water is not an element, but it is a very pure water, without ions in solution.
Is distilled water the same as deionized water?
No, distilled water and deionized water are not the same. Distilled water is created by boiling water and collecting the steam, while deionized water is purified by removing ions and minerals.
What is the resistivity of deionized water?
The resistivity of deionized water is typically around 18.2 megaohm-cm.
Is carbon dioxide is a basic oxide?
No, it is weakly acidic, forming carbonate and bicarbonate salts.
Is medicne acid or alkali?
Normally medicines are not highly acidic or basic. They are mainly weakly acidic or basic substances or salt of weakly acidic or basic substances. Only a few drugs are acidic or basic.The properties of the medicines are depends on the route of administration and target area of the drug.
