Therefore, any metal which is below hydrogen on the 'activity series' won't react because the metal refuses to be oxidized by the hydrogen atom alone. If you look at the relative strengths of acids, you'll see that nitric acid (HNO3) is actually 'weaker' than HCl is, however nitric a...
What ions makes urine more acidic or basic? a. Hydrogen b. Bicarbonate c. Both of them d. None of them pH: pH is a measurement of the concentration of hydrogen ions present in a solution. The higher the H+ concentration, the lower the pH and the...
While aluminum shares many properties with metals (conducting electricity and heat, shine), it's got some unique properties as well, which comes from its location in the periodic table. Since it's closer to the non-metals than the transition metals, its properties are somewhat transient. For ...
Check which is the most acidic hydrogen in the molecule. Decide the most acidic hydrogen in the given molecule. Which of the following four compounds is the most acidic (i.e., has the lowest pKa value)? How can i know whether solution is acidic or not and then what type of acid?
According to Arrhenius, acids are compounds that break up in water to give off hydronium (H+) ions. A common example of an Arrhenius acid is hydrochloric acid (HCl): HCl ⇔ H+ + Cl- The formulas for acids usually start with hydrogen, though organic acids are a notable exception. The...
Hydrogen is the simplest chemical element, or type of atom. It consists of just one proton and one electron. It is also the most abundant element, making up around 75% of the known matter in the universe. Vast amounts of hydrogen exist in water and living things. ...
and a potent acid when dissolved in water. While hydrogen iodide exists as a gas, hydroiodic acid is its aqueous solution. These forms can interconvert. Widely used as a reducing agent and a source of iodine, hydrogen iodide plays a vital role in the production of various compounds. ...
What is the pH of an acidic solution that has a hydrogen ion concentration of {eq}2.3 \times 10^{-3} {/eq} M? a. 2.6 b. 11.4 c. 3 d. 11Acidic Solution:Suppose we have a mathematical expression {eq}\displaystyle m\times n {/eq} ...
