Sir I have confusion...ph scale H+ ions dekhta h ya OH ions aur oH jyada hoga to acid hoga ya base

[@insightssb]

The strength of acids and bases depends on the number of H+ ions and OH- ions produced, respectively. If we take hydrochloric acid and acetic acid of the same concentration, say one molar, then these produce different amounts of hydrogen ions. Acids that give rise to more H+ ionsare said to be strong acids, and acids that give less H+ ions are said to be weak acids

[@PrashantSingh-tu2sr]

Tq सर

[@meditationhub77]

more no. of OH- means stronger base...less no. of OH ions mean weak base

[@anuragustus]

Sir it's Rutherford who discovered proton not Goldstein

[@aryamanchoudhary7376]

Well technically, Goldstein did come up with the concept of a positively charged particle in an atom much earlier than Rutherford, hence he is said to have co-discovered the proton

[@twinkler2854]

Observed as H+ by Eugen Goldstein (1886). Identified in other nuclei (and named) by Ernest Rutherford (1917-1920). Wikipedia says this. It's quite confusing, maybe upsc won't put both Goldstein and Rutherford for proton but that's just my guess

Thanks for this..... but we need the same for English too

[@AMITSINGH3j]

5:13 there should be sodium and calcium instead of Mg and Ca

[@insightssb]

Calcium and magnesium are two metals that start floating after some time when immersed in water. The bubbles of the hydrogen gas so formed in the reaction stick to the surface of the metal surface, and thus the metals float on water.
