is another strong acid.Nitric acid has a pH of 2.The teacher adds enough water to reduce the concentration of the nitric acid by a factor of 100.Calculate the new pH of the nitric acid.pH ...2](ii) Nitric acid, HNO , can also neutralise sodium hydroxide, NaOH.Sodium nitrate, NaNO3...
NaOH does this as it dissociates into {eq}\rm Na^+ {/eq} and {eq}\rm OH^- {/eq} with the hydroxide group reacting with the hydrogen. A strong base will dissociate completely.Answer and Explanation: The reaction for the dissociation of NaOH in water looks like this: {eq}\rm NaOH...
If the Ph value of the staining solution is kept at about 4.0,the quality of Pap staining can be significantly improved.%目的 探讨EA50染液pH值变化对宫颈脱落细胞染色的影响,寻求提高巴氏染色质量的方法.方法 用1 mol/L Na2CO3和1 mol/L HAC分别处理EA50染液,测定其pH值,观察宫颈脱落细胞在不同pH值...
If we have a solution that is made up of a base (such as NaOH), we can easily calculate the concentration of the hydroxide ion. The concentration of the hydroxide ion will help us know the pOH value of the solution. The pOH value is necessary to determine the pH value. ...
