What is the meaning of ''the desired pH adjusted using drops ... - Socratic
The N should read M. M means molarity (concentration). Or more specifically mol.dm^-3. You could adjust pH using 2M HCl (Hydrochloric acid) or 2M NaOH (Sodium Hydroxide). If the pH of your glucose solution is too low (i.e. too acidic) you could add drops of 2M NaOH until the desired pH is reached. This is because you are adding a base (:OH^- ions from NaOH) to an acidic solution and are ...
What is the product of the following reaction? 1)CH_3 OH - Socratic
These are ostensibly acid-base reactions.... For ammonium we could write.... NH_4^+ +HO^(-) rarr NH_3(aq) + H_2O(l) For methanol, the acid base reaction would proceed ...
Question #a9dd1 + Example - Socratic
There are many, but the two you're likely being asked for are: Hydroxide (OH^-) Ammonium (NH_4^+) There are many polyatomic ions that don't end in "-ite" or "-ate". For example: Hydroxide (OH^-) Ammonium (NH_4^+) Cyanide (CN^-) Peroxide (O_2^(2-)) The first 2 are likely the ones that you're being asked for -- they're extremely common across general chemistry, and it will do you credit to have ...
Question #a87b0 - Socratic
Strong Base collection => Group IA and Group IIA Hydroxides (Except for Beryllium Hydroxide) can be titrated with strong acid such that concentration of Alkali-Hydroxide = concentration of Hydroxide ion in solution & indicates 100% dissociation. Starting with say 1.0 mole/Liter NaOH in aqueous solution and titrating to end point with strong acid ( ~HCl(aq)) gives concentration of the Hydroxide ...
Question #d9b58 - Socratic
Explanation: #H_3PO_4 (aq)+Ca (OH)_2 (aq) rarr Ca_3 (PO_4)_2+H_2O (l)#
How many moles of KOH are there in 1.673x1023 molecules oh KOH? - Socratic
How many moles of KOH are there in 1.673x1023 molecules oh KOH?
Question #8556c - Socratic
This means that the anilinium ion is a reasonably strong conjugate acid producing higher degree of hydrolytic effect than the Nitrite ion which => # [H^+] > [OH^-]# => pH < 7 (acidic).
Question #93f99 - Socratic
The molarity of the acid is 1.434. Start with the equation: 2HNO_ (3 (aq))+Ca (OH)_ (2 (aq))rarrCa (NO_3)_ (2 (aq))+2H_2O_ ( (l)) This tells us that 2 moles of HNO_3 ...
Which pH paper and pH meter that are used for detect the pH ... - Socratic
pH refers to the relative concentration of H^+ and OH^- in aqueous (water-based) solution, and does not really apply to oils. As pointed out, pH does not really apply to non-aqueous solutions. Oils can entrain water, which (or so am I told) can support concentrations of hydrogen sulfide, which can act as a weak acid in water. Other than this you are going to have to find a better informed ...
How do I find pH and pOH for solutions of aqueous hydrogen ... - Socratic
You have the measurements, but you must use the definitions of pH and pOH. On the basis of the data given, you cannot measure pH for the basic sodium fluoride solution. Water dissociates according to the following equilibrium: 2H_2O rightleftharpoonsH_3O^+ +HO^- Now it is well known that for a given temperature, the extent of this autoprotolysis reaction is a constant: K_w=([H_3O^+][HO^-])/([H ...
